Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465702, here are decompositions:

5 + 31465697 = 31465702
29 + 31465673 = 31465702
41 + 31465661 = 31465702
53 + 31465649 = 31465702
71 + 31465631 = 31465702
83 + 31465619 = 31465702
101 + 31465601 = 31465702
131 + 31465571 = 31465702

Showing the first eight; more decompositions exist.
