Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931028, here are decompositions:

37 + 930991 = 931028
97 + 930931 = 931028
139 + 930889 = 931028
181 + 930847 = 931028
211 + 930817 = 931028
409 + 930619 = 931028
457 + 930571 = 931028
547 + 930481 = 931028

Showing the first eight; more decompositions exist.
