Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931540, here are decompositions:

3 + 931537 = 931540
11 + 931529 = 931540
23 + 931517 = 931540
41 + 931499 = 931540
53 + 931487 = 931540
227 + 931313 = 931540
251 + 931289 = 931540
347 + 931193 = 931540

Showing the first eight; more decompositions exist.
