Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465864, here are decompositions:

83 + 31465781 = 31465864
107 + 31465757 = 31465864
137 + 31465727 = 31465864
167 + 31465697 = 31465864
191 + 31465673 = 31465864
233 + 31465631 = 31465864
263 + 31465601 = 31465864
293 + 31465571 = 31465864

Showing the first eight; more decompositions exist.
