Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1039838, here are decompositions:

157 + 1039681 = 1039838
181 + 1039657 = 1039838
409 + 1039429 = 1039838
487 + 1039351 = 1039838
727 + 1039111 = 1039838
757 + 1039081 = 1039838
769 + 1039069 = 1039838
1117 + 1038721 = 1039838

Showing the first eight; more decompositions exist.
