Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647044, here are decompositions:

13 + 8647031 = 8647044
17 + 8647027 = 8647044
23 + 8647021 = 8647044
37 + 8647007 = 8647044
73 + 8646971 = 8647044
83 + 8646961 = 8647044
97 + 8646947 = 8647044
101 + 8646943 = 8647044

Showing the first eight; more decompositions exist.
