Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624738, here are decompositions:

61 + 8624677 = 8624738
139 + 8624599 = 8624738
487 + 8624251 = 8624738
547 + 8624191 = 8624738
601 + 8624137 = 8624738
607 + 8624131 = 8624738
769 + 8623969 = 8624738
907 + 8623831 = 8624738

Showing the first eight; more decompositions exist.
