Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649692, here are decompositions:

3 + 8649689 = 8649692
31 + 8649661 = 8649692
223 + 8649469 = 8649692
229 + 8649463 = 8649692
241 + 8649451 = 8649692
283 + 8649409 = 8649692
349 + 8649343 = 8649692
409 + 8649283 = 8649692

Showing the first eight; more decompositions exist.
