Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596726, here are decompositions:

13 + 31596713 = 31596726
17 + 31596709 = 31596726
19 + 31596707 = 31596726
47 + 31596679 = 31596726
53 + 31596673 = 31596726
89 + 31596637 = 31596726
113 + 31596613 = 31596726
173 + 31596553 = 31596726

Showing the first eight; more decompositions exist.
