Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1039280, here are decompositions:

31 + 1039249 = 1039280
127 + 1039153 = 1039280
199 + 1039081 = 1039280
211 + 1039069 = 1039280
241 + 1039039 = 1039280
367 + 1038913 = 1039280
457 + 1038823 = 1039280
523 + 1038757 = 1039280

Showing the first eight; more decompositions exist.
