Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656460, here are decompositions:

37 + 8656423 = 8656460
61 + 8656399 = 8656460
67 + 8656393 = 8656460
97 + 8656363 = 8656460
103 + 8656357 = 8656460
139 + 8656321 = 8656460
181 + 8656279 = 8656460
229 + 8656231 = 8656460

Showing the first eight; more decompositions exist.
