Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495322, here are decompositions:

109 + 31495213 = 31495322
151 + 31495171 = 31495322
373 + 31494949 = 31495322
379 + 31494943 = 31495322
541 + 31494781 = 31495322
601 + 31494721 = 31495322
631 + 31494691 = 31495322
643 + 31494679 = 31495322

Showing the first eight; more decompositions exist.
