Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463670, here are decompositions:

79 + 31463591 = 31463670
83 + 31463587 = 31463670
137 + 31463533 = 31463670
151 + 31463519 = 31463670
163 + 31463507 = 31463670
181 + 31463489 = 31463670
193 + 31463477 = 31463670
211 + 31463459 = 31463670

Showing the first eight; more decompositions exist.
