Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624540, here are decompositions:

37 + 8624503 = 8624540
157 + 8624383 = 8624540
229 + 8624311 = 8624540
349 + 8624191 = 8624540
409 + 8624131 = 8624540
439 + 8624101 = 8624540
523 + 8624017 = 8624540
571 + 8623969 = 8624540

Showing the first eight; more decompositions exist.
