Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657698, here are decompositions:

11 + 8657687 = 8657698
17 + 8657681 = 8657698
47 + 8657651 = 8657698
59 + 8657639 = 8657698
131 + 8657567 = 8657698
311 + 8657387 = 8657698
317 + 8657381 = 8657698
389 + 8657309 = 8657698

Showing the first eight; more decompositions exist.
