Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042680, here are decompositions:

47 + 1042633 = 1042680
61 + 1042619 = 1042680
71 + 1042609 = 1042680
73 + 1042607 = 1042680
83 + 1042597 = 1042680
97 + 1042583 = 1042680
103 + 1042577 = 1042680
109 + 1042571 = 1042680

Showing the first eight; more decompositions exist.
