Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656628, here are decompositions:

67 + 8656561 = 8656628
151 + 8656477 = 8656628
229 + 8656399 = 8656628
271 + 8656357 = 8656628
307 + 8656321 = 8656628
349 + 8656279 = 8656628
397 + 8656231 = 8656628
439 + 8656189 = 8656628

Showing the first eight; more decompositions exist.
