Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638074, here are decompositions:

7 + 8638067 = 8638074
13 + 8638061 = 8638074
23 + 8638051 = 8638074
31 + 8638043 = 8638074
41 + 8638033 = 8638074
83 + 8637991 = 8638074
101 + 8637973 = 8638074
131 + 8637943 = 8638074

Showing the first eight; more decompositions exist.
