Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464882, here are decompositions:

61 + 31464821 = 31464882
73 + 31464809 = 31464882
101 + 31464781 = 31464882
151 + 31464731 = 31464882
173 + 31464709 = 31464882
181 + 31464701 = 31464882
233 + 31464649 = 31464882
263 + 31464619 = 31464882

Showing the first eight; more decompositions exist.
