Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655656, here are decompositions:

3 + 8655653 = 8655656
7 + 8655649 = 8655656
19 + 8655637 = 8655656
199 + 8655457 = 8655656
223 + 8655433 = 8655656
307 + 8655349 = 8655656
313 + 8655343 = 8655656
349 + 8655307 = 8655656

Showing the first eight; more decompositions exist.
