Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645698, here are decompositions:

11 + 8645687 = 8645698
29 + 8645669 = 8645698
41 + 8645657 = 8645698
101 + 8645597 = 8645698
317 + 8645381 = 8645698
431 + 8645267 = 8645698
461 + 8645237 = 8645698
557 + 8645141 = 8645698

Showing the first eight; more decompositions exist.
