Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465486, here are decompositions:

5 + 31465481 = 31465486
197 + 31465289 = 31465486
263 + 31465223 = 31465486
293 + 31465193 = 31465486
659 + 31464827 = 31465486
677 + 31464809 = 31465486
929 + 31464557 = 31465486
977 + 31464509 = 31465486

Showing the first eight; more decompositions exist.
