Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931090, here are decompositions:

3 + 931087 = 931090
23 + 931067 = 931090
101 + 930989 = 931090
113 + 930977 = 931090
179 + 930911 = 931090
227 + 930863 = 931090
263 + 930827 = 931090
311 + 930779 = 931090

Showing the first eight; more decompositions exist.
