Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596782, here are decompositions:

13 + 31596769 = 31596782
31 + 31596751 = 31596782
73 + 31596709 = 31596782
103 + 31596679 = 31596782
109 + 31596673 = 31596782
199 + 31596583 = 31596782
211 + 31596571 = 31596782
229 + 31596553 = 31596782

Showing the first eight; more decompositions exist.
