Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623688, here are decompositions:

37 + 8623651 = 8623688
67 + 8623621 = 8623688
109 + 8623579 = 8623688
331 + 8623357 = 8623688
349 + 8623339 = 8623688
397 + 8623291 = 8623688
439 + 8623249 = 8623688
547 + 8623141 = 8623688

Showing the first eight; more decompositions exist.
