Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465966, here are decompositions:

137 + 31465829 = 31465966
239 + 31465727 = 31465966
269 + 31465697 = 31465966
293 + 31465673 = 31465966
317 + 31465649 = 31465966
347 + 31465619 = 31465966
419 + 31465547 = 31465966
677 + 31465289 = 31465966

Showing the first eight; more decompositions exist.
