Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656548, here are decompositions:

11 + 8656537 = 8656548
31 + 8656517 = 8656548
37 + 8656511 = 8656548
67 + 8656481 = 8656548
71 + 8656477 = 8656548
79 + 8656469 = 8656548
137 + 8656411 = 8656548
149 + 8656399 = 8656548

Showing the first eight; more decompositions exist.
