Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464810, here are decompositions:

23 + 31464787 = 31464810
29 + 31464781 = 31464810
53 + 31464757 = 31464810
79 + 31464731 = 31464810
101 + 31464709 = 31464810
109 + 31464701 = 31464810
191 + 31464619 = 31464810
193 + 31464617 = 31464810

Showing the first eight; more decompositions exist.
