Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623938, here are decompositions:

41 + 8623897 = 8623938
107 + 8623831 = 8623938
131 + 8623807 = 8623938
137 + 8623801 = 8623938
139 + 8623799 = 8623938
151 + 8623787 = 8623938
181 + 8623757 = 8623938
251 + 8623687 = 8623938

Showing the first eight; more decompositions exist.
