Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1043072, here are decompositions:

61 + 1043011 = 1043072
211 + 1042861 = 1043072
223 + 1042849 = 1043072
313 + 1042759 = 1043072
379 + 1042693 = 1043072
439 + 1042633 = 1043072
463 + 1042609 = 1043072
673 + 1042399 = 1043072

Showing the first eight; more decompositions exist.
