Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464722, here are decompositions:

13 + 31464709 = 31464722
73 + 31464649 = 31464722
103 + 31464619 = 31464722
151 + 31464571 = 31464722
229 + 31464493 = 31464722
241 + 31464481 = 31464722
271 + 31464451 = 31464722
283 + 31464439 = 31464722

Showing the first eight; more decompositions exist.
