Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042786, here are decompositions:

5 + 1042781 = 1042786
53 + 1042733 = 1042786
83 + 1042703 = 1042786
167 + 1042619 = 1042786
179 + 1042607 = 1042786
257 + 1042529 = 1042786
263 + 1042523 = 1042786
317 + 1042469 = 1042786

Showing the first eight; more decompositions exist.
