Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624572, here are decompositions:

113 + 8624459 = 8624572
179 + 8624393 = 8624572
389 + 8624183 = 8624572
419 + 8624153 = 8624572
431 + 8624141 = 8624572
443 + 8624129 = 8624572
461 + 8624111 = 8624572
521 + 8624051 = 8624572

Showing the first eight; more decompositions exist.
