Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624942, here are decompositions:

13 + 8624929 = 8624942
61 + 8624881 = 8624942
229 + 8624713 = 8624942
439 + 8624503 = 8624942
619 + 8624323 = 8624942
631 + 8624311 = 8624942
691 + 8624251 = 8624942
751 + 8624191 = 8624942

Showing the first eight; more decompositions exist.
