Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590794, here are decompositions:

3 + 31590791 = 31590794
31 + 31590763 = 31590794
61 + 31590733 = 31590794
127 + 31590667 = 31590794
163 + 31590631 = 31590794
211 + 31590583 = 31590794
223 + 31590571 = 31590794
307 + 31590487 = 31590794

Showing the first eight; more decompositions exist.
