Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656624, here are decompositions:

47 + 8656577 = 8656624
101 + 8656523 = 8656624
107 + 8656517 = 8656624
113 + 8656511 = 8656624
131 + 8656493 = 8656624
191 + 8656433 = 8656624
257 + 8656367 = 8656624
311 + 8656313 = 8656624

Showing the first eight; more decompositions exist.
