Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038680, here are decompositions:

37 + 1038643 = 1038680
43 + 1038637 = 1038680
61 + 1038619 = 1038680
79 + 1038601 = 1038680
151 + 1038529 = 1038680
157 + 1038523 = 1038680
193 + 1038487 = 1038680
271 + 1038409 = 1038680

Showing the first eight; more decompositions exist.
