Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706656, here are decompositions:

43 + 8706613 = 8706656
103 + 8706553 = 8706656
109 + 8706547 = 8706656
193 + 8706463 = 8706656
199 + 8706457 = 8706656
307 + 8706349 = 8706656
367 + 8706289 = 8706656
373 + 8706283 = 8706656

Showing the first eight; more decompositions exist.
