Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624656, here are decompositions:

23 + 8624633 = 8624656
83 + 8624573 = 8624656
149 + 8624507 = 8624656
179 + 8624477 = 8624656
197 + 8624459 = 8624656
263 + 8624393 = 8624656
389 + 8624267 = 8624656
419 + 8624237 = 8624656

Showing the first eight; more decompositions exist.
