Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464672, here are decompositions:

23 + 31464649 = 31464672
53 + 31464619 = 31464672
101 + 31464571 = 31464672
163 + 31464509 = 31464672
179 + 31464493 = 31464672
191 + 31464481 = 31464672
229 + 31464443 = 31464672
233 + 31464439 = 31464672

Showing the first eight; more decompositions exist.
