Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638070, here are decompositions:

3 + 8638067 = 8638070
19 + 8638051 = 8638070
31 + 8638039 = 8638070
37 + 8638033 = 8638070
79 + 8637991 = 8638070
97 + 8637973 = 8638070
127 + 8637943 = 8638070
223 + 8637847 = 8638070

Showing the first eight; more decompositions exist.
