Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931828, here are decompositions:

17 + 931811 = 931828
47 + 931781 = 931828
71 + 931757 = 931828
89 + 931739 = 931828
101 + 931727 = 931828
137 + 931691 = 931828
251 + 931577 = 931828
257 + 931571 = 931828

Showing the first eight; more decompositions exist.
