Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647074, here are decompositions:

11 + 8647063 = 8647074
13 + 8647061 = 8647074
31 + 8647043 = 8647074
43 + 8647031 = 8647074
47 + 8647027 = 8647074
53 + 8647021 = 8647074
67 + 8647007 = 8647074
103 + 8646971 = 8647074

Showing the first eight; more decompositions exist.
