Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465744, here are decompositions:

3 + 31465741 = 31465744
17 + 31465727 = 31465744
47 + 31465697 = 31465744
71 + 31465673 = 31465744
83 + 31465661 = 31465744
113 + 31465631 = 31465744
173 + 31465571 = 31465744
197 + 31465547 = 31465744

Showing the first eight; more decompositions exist.
