Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624786, here are decompositions:

13 + 8624773 = 8624786
73 + 8624713 = 8624786
109 + 8624677 = 8624786
283 + 8624503 = 8624786
337 + 8624449 = 8624786
433 + 8624353 = 8624786
463 + 8624323 = 8624786
607 + 8624179 = 8624786

Showing the first eight; more decompositions exist.
