Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623894, here are decompositions:

11 + 8623883 = 8623894
47 + 8623847 = 8623894
101 + 8623793 = 8623894
107 + 8623787 = 8623894
131 + 8623763 = 8623894
137 + 8623757 = 8623894
173 + 8623721 = 8623894
233 + 8623661 = 8623894

Showing the first eight; more decompositions exist.
