Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464736, here are decompositions:

5 + 31464731 = 31464736
179 + 31464557 = 31464736
227 + 31464509 = 31464736
293 + 31464443 = 31464736
467 + 31464269 = 31464736
503 + 31464233 = 31464736
587 + 31464149 = 31464736
593 + 31464143 = 31464736

Showing the first eight; more decompositions exist.
