Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657628, here are decompositions:

17 + 8657611 = 8657628
59 + 8657569 = 8657628
61 + 8657567 = 8657628
71 + 8657557 = 8657628
167 + 8657461 = 8657628
179 + 8657449 = 8657628
197 + 8657431 = 8657628
241 + 8657387 = 8657628

Showing the first eight; more decompositions exist.
