Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628664, here are decompositions:

3 + 8628661 = 8628664
17 + 8628647 = 8628664
41 + 8628623 = 8628664
113 + 8628551 = 8628664
257 + 8628407 = 8628664
281 + 8628383 = 8628664
311 + 8628353 = 8628664
431 + 8628233 = 8628664

Showing the first eight; more decompositions exist.
