Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465814, here are decompositions:

13 + 31465801 = 31465814
67 + 31465747 = 31465814
73 + 31465741 = 31465814
103 + 31465711 = 31465814
151 + 31465663 = 31465814
397 + 31465417 = 31465814
571 + 31465243 = 31465814
631 + 31465183 = 31465814

Showing the first eight; more decompositions exist.
