Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624624, here are decompositions:

3 + 8624621 = 8624624
7 + 8624617 = 8624624
241 + 8624383 = 8624624
271 + 8624353 = 8624624
313 + 8624311 = 8624624
373 + 8624251 = 8624624
433 + 8624191 = 8624624
487 + 8624137 = 8624624

Showing the first eight; more decompositions exist.
