Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012742, here are decompositions:

43 + 1012699 = 1012742
79 + 1012663 = 1012742
109 + 1012633 = 1012742
151 + 1012591 = 1012742
193 + 1012549 = 1012742
223 + 1012519 = 1012742
229 + 1012513 = 1012742
331 + 1012411 = 1012742

Showing the first eight; more decompositions exist.
