Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465996, here are decompositions:

17 + 31465979 = 31465996
167 + 31465829 = 31465996
239 + 31465757 = 31465996
269 + 31465727 = 31465996
347 + 31465649 = 31465996
449 + 31465547 = 31465996
467 + 31465529 = 31465996
773 + 31465223 = 31465996

Showing the first eight; more decompositions exist.
