Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647528, here are decompositions:

17 + 8647511 = 8647528
59 + 8647469 = 8647528
137 + 8647391 = 8647528
179 + 8647349 = 8647528
251 + 8647277 = 8647528
347 + 8647181 = 8647528
389 + 8647139 = 8647528
401 + 8647127 = 8647528

Showing the first eight; more decompositions exist.
