Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688946, here are decompositions:

3 + 8688943 = 8688946
83 + 8688863 = 8688946
137 + 8688809 = 8688946
239 + 8688707 = 8688946
317 + 8688629 = 8688946
353 + 8688593 = 8688946
389 + 8688557 = 8688946
419 + 8688527 = 8688946

Showing the first eight; more decompositions exist.
