Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1043742, here are decompositions:

19 + 1043723 = 1043742
41 + 1043701 = 1043742
59 + 1043683 = 1043742
79 + 1043663 = 1043742
103 + 1043639 = 1043742
149 + 1043593 = 1043742
151 + 1043591 = 1043742
199 + 1043543 = 1043742

Showing the first eight; more decompositions exist.
