Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464516, here are decompositions:

7 + 31464509 = 31464516
23 + 31464493 = 31464516
53 + 31464463 = 31464516
73 + 31464443 = 31464516
89 + 31464427 = 31464516
107 + 31464409 = 31464516
157 + 31464359 = 31464516
283 + 31464233 = 31464516

Showing the first eight; more decompositions exist.
