Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624720, here are decompositions:

3 + 8624717 = 8624720
7 + 8624713 = 8624720
43 + 8624677 = 8624720
103 + 8624617 = 8624720
271 + 8624449 = 8624720
337 + 8624383 = 8624720
367 + 8624353 = 8624720
397 + 8624323 = 8624720

Showing the first eight; more decompositions exist.
