Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931786, here are decompositions:

3 + 931783 = 931786
5 + 931781 = 931786
29 + 931757 = 931786
47 + 931739 = 931786
59 + 931727 = 931786
257 + 931529 = 931786
269 + 931517 = 931786
467 + 931319 = 931786

Showing the first eight; more decompositions exist.
