Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042686, here are decompositions:

5 + 1042681 = 1042686
53 + 1042633 = 1042686
67 + 1042619 = 1042686
79 + 1042607 = 1042686
89 + 1042597 = 1042686
103 + 1042583 = 1042686
109 + 1042577 = 1042686
157 + 1042529 = 1042686

Showing the first eight; more decompositions exist.
