Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656722, here are decompositions:

31 + 8656691 = 8656722
149 + 8656573 = 8656722
199 + 8656523 = 8656722
211 + 8656511 = 8656722
223 + 8656499 = 8656722
229 + 8656493 = 8656722
241 + 8656481 = 8656722
311 + 8656411 = 8656722

Showing the first eight; more decompositions exist.
