Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596856, here are decompositions:

17 + 31596839 = 31596856
59 + 31596797 = 31596856
107 + 31596749 = 31596856
113 + 31596743 = 31596856
149 + 31596707 = 31596856
359 + 31596497 = 31596856
383 + 31596473 = 31596856
419 + 31596437 = 31596856

Showing the first eight; more decompositions exist.
