Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596390, here are decompositions:

11 + 31596379 = 31596390
73 + 31596317 = 31596390
79 + 31596311 = 31596390
83 + 31596307 = 31596390
97 + 31596293 = 31596390
181 + 31596209 = 31596390
197 + 31596193 = 31596390
227 + 31596163 = 31596390

Showing the first eight; more decompositions exist.
