Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931816, here are decompositions:

5 + 931811 = 931816
59 + 931757 = 931816
89 + 931727 = 931816
107 + 931709 = 931816
239 + 931577 = 931816
317 + 931499 = 931816
503 + 931313 = 931816
617 + 931199 = 931816

Showing the first eight; more decompositions exist.
