Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465468, here are decompositions:

17 + 31465451 = 31465468
179 + 31465289 = 31465468
521 + 31464947 = 31465468
641 + 31464827 = 31465468
647 + 31464821 = 31465468
659 + 31464809 = 31465468
887 + 31464581 = 31465468
911 + 31464557 = 31465468

Showing the first eight; more decompositions exist.
