Narrative:

When we started out of altitude (FL400); descending to destination; the auto-throttles disconnected and we noticed the number 1 engine rolling back. The engine automatically started a re-light. The engine came back with some notice of vibration. We monitored the engine parameters for the remainder of the trip. We declared PIC authority under far 91.3 with ATC and asked to land at an alternate airport. The controller came back and advised us that the alternate airport was closed. The controller the suggested we use another airport; which we then asked current weather there; which was freezing rain. Since we seemed to have control of the engine; we opted to continue to original destination with priority handling. The number 1 engine vibrations were higher than normal and I made slow power adjustments as needed. We landed in normal configuration with no events. We cancelled our status after we cleared the runway.
