Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649656, here are decompositions:

19 + 8649637 = 8649656
139 + 8649517 = 8649656
193 + 8649463 = 8649656
307 + 8649349 = 8649656
313 + 8649343 = 8649656
373 + 8649283 = 8649656
577 + 8649079 = 8649656
607 + 8649049 = 8649656

Showing the first eight; more decompositions exist.
