Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628718, here are decompositions:

41 + 8628677 = 8628718
71 + 8628647 = 8628718
89 + 8628629 = 8628718
167 + 8628551 = 8628718
239 + 8628479 = 8628718
269 + 8628449 = 8628718
311 + 8628407 = 8628718
359 + 8628359 = 8628718

Showing the first eight; more decompositions exist.
