Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690656, here are decompositions:

17 + 8690639 = 8690656
53 + 8690603 = 8690656
89 + 8690567 = 8690656
167 + 8690489 = 8690656
179 + 8690477 = 8690656
257 + 8690399 = 8690656
269 + 8690387 = 8690656
353 + 8690303 = 8690656

Showing the first eight; more decompositions exist.
