Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465914, here are decompositions:

23 + 31465891 = 31465914
83 + 31465831 = 31465914
113 + 31465801 = 31465914
157 + 31465757 = 31465914
167 + 31465747 = 31465914
173 + 31465741 = 31465914
241 + 31465673 = 31465914
251 + 31465663 = 31465914

Showing the first eight; more decompositions exist.
