Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621652, here are decompositions:

29 + 8621623 = 8621652
43 + 8621609 = 8621652
71 + 8621581 = 8621652
101 + 8621551 = 8621652
173 + 8621479 = 8621652
199 + 8621453 = 8621652
223 + 8621429 = 8621652
239 + 8621413 = 8621652

Showing the first eight; more decompositions exist.
