Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042790, here are decompositions:

31 + 1042759 = 1042790
97 + 1042693 = 1042790
103 + 1042687 = 1042790
109 + 1042681 = 1042790
157 + 1042633 = 1042790
181 + 1042609 = 1042790
193 + 1042597 = 1042790
271 + 1042519 = 1042790

Showing the first eight; more decompositions exist.
