Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539322, here are decompositions:

131 + 31539191 = 31539322
179 + 31539143 = 31539322
233 + 31539089 = 31539322
239 + 31539083 = 31539322
569 + 31538753 = 31539322
593 + 31538729 = 31539322
743 + 31538579 = 31539322
761 + 31538561 = 31539322

Showing the first eight; more decompositions exist.
