Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738966, here are decompositions:

3 + 8738963 = 8738966
37 + 8738929 = 8738966
127 + 8738839 = 8738966
157 + 8738809 = 8738966
199 + 8738767 = 8738966
307 + 8738659 = 8738966
433 + 8738533 = 8738966
673 + 8738293 = 8738966

Showing the first eight; more decompositions exist.
