Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623972, here are decompositions:

3 + 8623969 = 8623972
11 + 8623961 = 8623972
89 + 8623883 = 8623972
173 + 8623799 = 8623972
179 + 8623793 = 8623972
251 + 8623721 = 8623972
293 + 8623679 = 8623972
311 + 8623661 = 8623972

Showing the first eight; more decompositions exist.
