Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596666, here are decompositions:

5 + 31596661 = 31596666
29 + 31596637 = 31596666
53 + 31596613 = 31596666
83 + 31596583 = 31596666
113 + 31596553 = 31596666
193 + 31596473 = 31596666
229 + 31596437 = 31596666
263 + 31596403 = 31596666

Showing the first eight; more decompositions exist.
