Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596700, here are decompositions:

29 + 31596671 = 31596700
89 + 31596611 = 31596700
227 + 31596473 = 31596700
263 + 31596437 = 31596700
281 + 31596419 = 31596700
383 + 31596317 = 31596700
389 + 31596311 = 31596700
491 + 31596209 = 31596700

Showing the first eight; more decompositions exist.
