Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1039538, here are decompositions:

61 + 1039477 = 1039538
109 + 1039429 = 1039538
151 + 1039387 = 1039538
211 + 1039327 = 1039538
457 + 1039081 = 1039538
499 + 1039039 = 1039538
601 + 1038937 = 1039538
727 + 1038811 = 1039538

Showing the first eight; more decompositions exist.
