Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624872, here are decompositions:

101 + 8624771 = 8624872
239 + 8624633 = 8624872
251 + 8624621 = 8624872
479 + 8624393 = 8624872
719 + 8624153 = 8624872
743 + 8624129 = 8624872
761 + 8624111 = 8624872
821 + 8624051 = 8624872

Showing the first eight; more decompositions exist.
