Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656524, here are decompositions:

7 + 8656517 = 8656524
13 + 8656511 = 8656524
31 + 8656493 = 8656524
43 + 8656481 = 8656524
47 + 8656477 = 8656524
61 + 8656463 = 8656524
101 + 8656423 = 8656524
113 + 8656411 = 8656524

Showing the first eight; more decompositions exist.
