Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931688, here are decompositions:

31 + 931657 = 931688
67 + 931621 = 931688
151 + 931537 = 931688
271 + 931417 = 931688
337 + 931351 = 931688
379 + 931309 = 931688
421 + 931267 = 931688
601 + 931087 = 931688

Showing the first eight; more decompositions exist.
