Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629918, here are decompositions:

29 + 8629889 = 8629918
71 + 8629847 = 8629918
179 + 8629739 = 8629918
239 + 8629679 = 8629918
257 + 8629661 = 8629918
281 + 8629637 = 8629918
509 + 8629409 = 8629918
569 + 8629349 = 8629918

Showing the first eight; more decompositions exist.
