Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656508, here are decompositions:

31 + 8656477 = 8656508
97 + 8656411 = 8656508
109 + 8656399 = 8656508
139 + 8656369 = 8656508
151 + 8656357 = 8656508
229 + 8656279 = 8656508
277 + 8656231 = 8656508
331 + 8656177 = 8656508

Showing the first eight; more decompositions exist.
