Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931858, here are decompositions:

47 + 931811 = 931858
101 + 931757 = 931858
107 + 931751 = 931858
131 + 931727 = 931858
149 + 931709 = 931858
167 + 931691 = 931858
281 + 931577 = 931858
359 + 931499 = 931858

Showing the first eight; more decompositions exist.
