Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647038, here are decompositions:

7 + 8647031 = 8647038
11 + 8647027 = 8647038
17 + 8647021 = 8647038
31 + 8647007 = 8647038
67 + 8646971 = 8647038
89 + 8646949 = 8647038
109 + 8646929 = 8647038
139 + 8646899 = 8647038

Showing the first eight; more decompositions exist.
