Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618652, here are decompositions:

13 + 8618639 = 8618652
59 + 8618593 = 8618652
61 + 8618591 = 8618652
71 + 8618581 = 8618652
151 + 8618501 = 8618652
173 + 8618479 = 8618652
223 + 8618429 = 8618652
239 + 8618413 = 8618652

Showing the first eight; more decompositions exist.
