Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638044, here are decompositions:

5 + 8638039 = 8638044
11 + 8638033 = 8638044
53 + 8637991 = 8638044
71 + 8637973 = 8638044
101 + 8637943 = 8638044
197 + 8637847 = 8638044
223 + 8637821 = 8638044
257 + 8637787 = 8638044

Showing the first eight; more decompositions exist.
