Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625418, here are decompositions:

59 + 8625359 = 8625418
101 + 8625317 = 8625418
107 + 8625311 = 8625418
227 + 8625191 = 8625418
359 + 8625059 = 8625418
419 + 8624999 = 8625418
647 + 8624771 = 8625418
701 + 8624717 = 8625418

Showing the first eight; more decompositions exist.
