Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596556, here are decompositions:

3 + 31596553 = 31596556
59 + 31596497 = 31596556
83 + 31596473 = 31596556
137 + 31596419 = 31596556
239 + 31596317 = 31596556
263 + 31596293 = 31596556
347 + 31596209 = 31596556
587 + 31595969 = 31596556

Showing the first eight; more decompositions exist.
