Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038686, here are decompositions:

43 + 1038643 = 1038686
67 + 1038619 = 1038686
97 + 1038589 = 1038686
157 + 1038529 = 1038686
163 + 1038523 = 1038686
199 + 1038487 = 1038686
223 + 1038463 = 1038686
277 + 1038409 = 1038686

Showing the first eight; more decompositions exist.
