Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596806, here are decompositions:

13 + 31596793 = 31596806
37 + 31596769 = 31596806
97 + 31596709 = 31596806
127 + 31596679 = 31596806
193 + 31596613 = 31596806
223 + 31596583 = 31596806
499 + 31596307 = 31596806
613 + 31596193 = 31596806

Showing the first eight; more decompositions exist.
