Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1043138, here are decompositions:

7 + 1043131 = 1043138
127 + 1043011 = 1043138
241 + 1042897 = 1043138
277 + 1042861 = 1043138
379 + 1042759 = 1043138
457 + 1042681 = 1043138
541 + 1042597 = 1043138
619 + 1042519 = 1043138

Showing the first eight; more decompositions exist.
