Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616656, here are decompositions:

3 + 8616653 = 8616656
109 + 8616547 = 8616656
157 + 8616499 = 8616656
163 + 8616493 = 8616656
199 + 8616457 = 8616656
277 + 8616379 = 8616656
283 + 8616373 = 8616656
337 + 8616319 = 8616656

Showing the first eight; more decompositions exist.
