Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623328, here are decompositions:

37 + 8623291 = 8623328
67 + 8623261 = 8623328
79 + 8623249 = 8623328
277 + 8623051 = 8623328
457 + 8622871 = 8623328
487 + 8622841 = 8623328
547 + 8622781 = 8623328
607 + 8622721 = 8623328

Showing the first eight; more decompositions exist.
