Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646628, here are decompositions:

47 + 8646581 = 8646628
131 + 8646497 = 8646628
149 + 8646479 = 8646628
227 + 8646401 = 8646628
239 + 8646389 = 8646628
251 + 8646377 = 8646628
311 + 8646317 = 8646628
359 + 8646269 = 8646628

Showing the first eight; more decompositions exist.
