Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465810, here are decompositions:

29 + 31465781 = 31465810
53 + 31465757 = 31465810
83 + 31465727 = 31465810
113 + 31465697 = 31465810
137 + 31465673 = 31465810
149 + 31465661 = 31465810
179 + 31465631 = 31465810
191 + 31465619 = 31465810

Showing the first eight; more decompositions exist.
