Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040742, here are decompositions:

11 + 1040731 = 1040742
71 + 1040671 = 1040742
83 + 1040659 = 1040742
113 + 1040629 = 1040742
163 + 1040579 = 1040742
179 + 1040563 = 1040742
211 + 1040531 = 1040742
239 + 1040503 = 1040742

Showing the first eight; more decompositions exist.
