Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617656, here are decompositions:

29 + 8617627 = 8617656
107 + 8617549 = 8617656
109 + 8617547 = 8617656
137 + 8617519 = 8617656
239 + 8617417 = 8617656
283 + 8617373 = 8617656
337 + 8617319 = 8617656
379 + 8617277 = 8617656

Showing the first eight; more decompositions exist.
