Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464768, here are decompositions:

11 + 31464757 = 31464768
37 + 31464731 = 31464768
59 + 31464709 = 31464768
67 + 31464701 = 31464768
149 + 31464619 = 31464768
151 + 31464617 = 31464768
191 + 31464577 = 31464768
197 + 31464571 = 31464768

Showing the first eight; more decompositions exist.
