Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624618, here are decompositions:

19 + 8624599 = 8624618
307 + 8624311 = 8624618
367 + 8624251 = 8624618
397 + 8624221 = 8624618
439 + 8624179 = 8624618
487 + 8624131 = 8624618
601 + 8624017 = 8624618
787 + 8623831 = 8624618

Showing the first eight; more decompositions exist.
