Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596640, here are decompositions:

3 + 31596637 = 31596640
29 + 31596611 = 31596640
167 + 31596473 = 31596640
227 + 31596413 = 31596640
239 + 31596401 = 31596640
347 + 31596293 = 31596640
431 + 31596209 = 31596640
521 + 31596119 = 31596640

Showing the first eight; more decompositions exist.
