Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647752, here are decompositions:

13 + 8647739 = 8647752
41 + 8647711 = 8647752
53 + 8647699 = 8647752
163 + 8647589 = 8647752
173 + 8647579 = 8647752
241 + 8647511 = 8647752
251 + 8647501 = 8647752
283 + 8647469 = 8647752

Showing the first eight; more decompositions exist.
