Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596670, here are decompositions:

59 + 31596611 = 31596670
173 + 31596497 = 31596670
197 + 31596473 = 31596670
233 + 31596437 = 31596670
251 + 31596419 = 31596670
257 + 31596413 = 31596670
269 + 31596401 = 31596670
353 + 31596317 = 31596670

Showing the first eight; more decompositions exist.
