Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464662, here are decompositions:

13 + 31464649 = 31464662
43 + 31464619 = 31464662
181 + 31464481 = 31464662
199 + 31464463 = 31464662
211 + 31464451 = 31464662
223 + 31464439 = 31464662
241 + 31464421 = 31464662
601 + 31464061 = 31464662

Showing the first eight; more decompositions exist.
