Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624660, here are decompositions:

43 + 8624617 = 8624660
61 + 8624599 = 8624660
157 + 8624503 = 8624660
211 + 8624449 = 8624660
277 + 8624383 = 8624660
307 + 8624353 = 8624660
337 + 8624323 = 8624660
349 + 8624311 = 8624660

Showing the first eight; more decompositions exist.
