Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042782, here are decompositions:

23 + 1042759 = 1042782
73 + 1042709 = 1042782
79 + 1042703 = 1042782
89 + 1042693 = 1042782
101 + 1042681 = 1042782
149 + 1042633 = 1042782
151 + 1042631 = 1042782
163 + 1042619 = 1042782

Showing the first eight; more decompositions exist.
