Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464762, here are decompositions:

5 + 31464757 = 31464762
31 + 31464731 = 31464762
53 + 31464709 = 31464762
61 + 31464701 = 31464762
113 + 31464649 = 31464762
181 + 31464581 = 31464762
191 + 31464571 = 31464762
269 + 31464493 = 31464762

Showing the first eight; more decompositions exist.
