Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464656, here are decompositions:

7 + 31464649 = 31464656
37 + 31464619 = 31464656
79 + 31464577 = 31464656
109 + 31464547 = 31464656
163 + 31464493 = 31464656
193 + 31464463 = 31464656
229 + 31464427 = 31464656
463 + 31464193 = 31464656

Showing the first eight; more decompositions exist.
