Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628994, here are decompositions:

71 + 8628923 = 8628994
137 + 8628857 = 8628994
317 + 8628677 = 8628994
347 + 8628647 = 8628994
443 + 8628551 = 8628994
587 + 8628407 = 8628994
617 + 8628377 = 8628994
641 + 8628353 = 8628994

Showing the first eight; more decompositions exist.
