Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464692, here are decompositions:

43 + 31464649 = 31464692
73 + 31464619 = 31464692
199 + 31464493 = 31464692
211 + 31464481 = 31464692
229 + 31464463 = 31464692
241 + 31464451 = 31464692
271 + 31464421 = 31464692
283 + 31464409 = 31464692

Showing the first eight; more decompositions exist.
