Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465962, here are decompositions:

71 + 31465891 = 31465962
83 + 31465879 = 31465962
113 + 31465849 = 31465962
131 + 31465831 = 31465962
173 + 31465789 = 31465962
181 + 31465781 = 31465962
251 + 31465711 = 31465962
313 + 31465649 = 31465962

Showing the first eight; more decompositions exist.
