Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638134, here are decompositions:

13 + 8638121 = 8638134
17 + 8638117 = 8638134
67 + 8638067 = 8638134
73 + 8638061 = 8638134
83 + 8638051 = 8638134
101 + 8638033 = 8638134
181 + 8637953 = 8638134
191 + 8637943 = 8638134

Showing the first eight; more decompositions exist.
