Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464780, here are decompositions:

23 + 31464757 = 31464780
71 + 31464709 = 31464780
79 + 31464701 = 31464780
131 + 31464649 = 31464780
163 + 31464617 = 31464780
199 + 31464581 = 31464780
223 + 31464557 = 31464780
233 + 31464547 = 31464780

Showing the first eight; more decompositions exist.
