Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464608, here are decompositions:

31 + 31464577 = 31464608
37 + 31464571 = 31464608
61 + 31464547 = 31464608
127 + 31464481 = 31464608
157 + 31464451 = 31464608
181 + 31464427 = 31464608
199 + 31464409 = 31464608
211 + 31464397 = 31464608

Showing the first eight; more decompositions exist.
