Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596396, here are decompositions:

5 + 31596391 = 31596396
17 + 31596379 = 31596396
79 + 31596317 = 31596396
89 + 31596307 = 31596396
103 + 31596293 = 31596396
233 + 31596163 = 31596396
269 + 31596127 = 31596396
277 + 31596119 = 31596396

Showing the first eight; more decompositions exist.
