Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623564, here are decompositions:

17 + 8623547 = 8623564
41 + 8623523 = 8623564
311 + 8623253 = 8623564
317 + 8623247 = 8623564
461 + 8623103 = 8623564
491 + 8623073 = 8623564
503 + 8623061 = 8623564
641 + 8622923 = 8623564

Showing the first eight; more decompositions exist.
