Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628658, here are decompositions:

11 + 8628647 = 8628658
29 + 8628629 = 8628658
107 + 8628551 = 8628658
179 + 8628479 = 8628658
251 + 8628407 = 8628658
281 + 8628377 = 8628658
509 + 8628149 = 8628658
641 + 8628017 = 8628658

Showing the first eight; more decompositions exist.
