Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630426, here are decompositions:

157 + 8630269 = 8630426
307 + 8630119 = 8630426
313 + 8630113 = 8630426
397 + 8630029 = 8630426
463 + 8629963 = 8630426
499 + 8629927 = 8630426
613 + 8629813 = 8630426
829 + 8629597 = 8630426

Showing the first eight; more decompositions exist.
