Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1039040, here are decompositions:

3 + 1039037 = 1039040
7 + 1039033 = 1039040
19 + 1039021 = 1039040
103 + 1038937 = 1039040
127 + 1038913 = 1039040
229 + 1038811 = 1039040
283 + 1038757 = 1039040
313 + 1038727 = 1039040

Showing the first eight; more decompositions exist.
