Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465910, here are decompositions:

19 + 31465891 = 31465910
31 + 31465879 = 31465910
61 + 31465849 = 31465910
79 + 31465831 = 31465910
109 + 31465801 = 31465910
163 + 31465747 = 31465910
199 + 31465711 = 31465910
331 + 31465579 = 31465910

Showing the first eight; more decompositions exist.
