Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931518, here are decompositions:

19 + 931499 = 931518
31 + 931487 = 931518
97 + 931421 = 931518
101 + 931417 = 931518
131 + 931387 = 931518
167 + 931351 = 931518
199 + 931319 = 931518
229 + 931289 = 931518

Showing the first eight; more decompositions exist.
