Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623966, here are decompositions:

3 + 8623963 = 8623966
5 + 8623961 = 8623966
83 + 8623883 = 8623966
167 + 8623799 = 8623966
173 + 8623793 = 8623966
179 + 8623787 = 8623966
347 + 8623619 = 8623966
383 + 8623583 = 8623966

Showing the first eight; more decompositions exist.
