Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931628, here are decompositions:

7 + 931621 = 931628
31 + 931597 = 931628
211 + 931417 = 931628
241 + 931387 = 931628
277 + 931351 = 931628
499 + 931129 = 931628
541 + 931087 = 931628
739 + 930889 = 931628

Showing the first eight; more decompositions exist.
