Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042690, here are decompositions:

3 + 1042687 = 1042690
59 + 1042631 = 1042690
71 + 1042619 = 1042690
83 + 1042607 = 1042690
107 + 1042583 = 1042690
113 + 1042577 = 1042690
167 + 1042523 = 1042690
239 + 1042451 = 1042690

Showing the first eight; more decompositions exist.
