Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464858, here are decompositions:

31 + 31464827 = 31464858
37 + 31464821 = 31464858
71 + 31464787 = 31464858
101 + 31464757 = 31464858
127 + 31464731 = 31464858
149 + 31464709 = 31464858
157 + 31464701 = 31464858
239 + 31464619 = 31464858

Showing the first eight; more decompositions exist.
