Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638698, here are decompositions:

7 + 8638691 = 8638698
11 + 8638687 = 8638698
37 + 8638661 = 8638698
71 + 8638627 = 8638698
181 + 8638517 = 8638698
227 + 8638471 = 8638698
241 + 8638457 = 8638698
251 + 8638447 = 8638698

Showing the first eight; more decompositions exist.
