Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647652, here are decompositions:

73 + 8647579 = 8647652
151 + 8647501 = 8647652
193 + 8647459 = 8647652
241 + 8647411 = 8647652
283 + 8647369 = 8647652
379 + 8647273 = 8647652
421 + 8647231 = 8647652
523 + 8647129 = 8647652

Showing the first eight; more decompositions exist.
