Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656698, here are decompositions:

7 + 8656691 = 8656698
31 + 8656667 = 8656698
109 + 8656589 = 8656698
137 + 8656561 = 8656698
151 + 8656547 = 8656698
181 + 8656517 = 8656698
199 + 8656499 = 8656698
229 + 8656469 = 8656698

Showing the first eight; more decompositions exist.
