Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464826, here are decompositions:

5 + 31464821 = 31464826
17 + 31464809 = 31464826
269 + 31464557 = 31464826
317 + 31464509 = 31464826
383 + 31464443 = 31464826
467 + 31464359 = 31464826
557 + 31464269 = 31464826
593 + 31464233 = 31464826

Showing the first eight; more decompositions exist.
