Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465750, here are decompositions:

3 + 31465747 = 31465750
23 + 31465727 = 31465750
53 + 31465697 = 31465750
89 + 31465661 = 31465750
101 + 31465649 = 31465750
131 + 31465619 = 31465750
149 + 31465601 = 31465750
179 + 31465571 = 31465750

Showing the first eight; more decompositions exist.
