Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644756, here are decompositions:

5 + 8644751 = 8644756
53 + 8644703 = 8644756
149 + 8644607 = 8644756
227 + 8644529 = 8644756
257 + 8644499 = 8644756
317 + 8644439 = 8644756
359 + 8644397 = 8644756
503 + 8644253 = 8644756

Showing the first eight; more decompositions exist.
