Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624648, here are decompositions:

31 + 8624617 = 8624648
199 + 8624449 = 8624648
337 + 8624311 = 8624648
397 + 8624251 = 8624648
457 + 8624191 = 8624648
547 + 8624101 = 8624648
631 + 8624017 = 8624648
709 + 8623939 = 8624648

Showing the first eight; more decompositions exist.
