Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931660, here are decompositions:

3 + 931657 = 931660
83 + 931577 = 931660
89 + 931571 = 931660
131 + 931529 = 931660
173 + 931487 = 931660
239 + 931421 = 931660
347 + 931313 = 931660
419 + 931241 = 931660

Showing the first eight; more decompositions exist.
