Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586796, here are decompositions:

5 + 31586791 = 31586796
53 + 31586743 = 31586796
79 + 31586717 = 31586796
89 + 31586707 = 31586796
97 + 31586699 = 31586796
107 + 31586689 = 31586796
127 + 31586669 = 31586796
149 + 31586647 = 31586796

Showing the first eight; more decompositions exist.
