Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623990, here are decompositions:

29 + 8623961 = 8623990
107 + 8623883 = 8623990
191 + 8623799 = 8623990
197 + 8623793 = 8623990
227 + 8623763 = 8623990
233 + 8623757 = 8623990
239 + 8623751 = 8623990
269 + 8623721 = 8623990

Showing the first eight; more decompositions exist.
