Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465066, here are decompositions:

5 + 31465061 = 31465066
239 + 31464827 = 31465066
257 + 31464809 = 31465066
449 + 31464617 = 31465066
509 + 31464557 = 31465066
557 + 31464509 = 31465066
797 + 31464269 = 31465066
929 + 31464137 = 31465066

Showing the first eight; more decompositions exist.
