Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465108, here are decompositions:

47 + 31465061 = 31465108
167 + 31464941 = 31465108
281 + 31464827 = 31465108
491 + 31464617 = 31465108
599 + 31464509 = 31465108
827 + 31464281 = 31465108
839 + 31464269 = 31465108
971 + 31464137 = 31465108

Showing the first eight; more decompositions exist.
