Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464568, here are decompositions:

11 + 31464557 = 31464568
59 + 31464509 = 31464568
167 + 31464401 = 31464568
227 + 31464341 = 31464568
419 + 31464149 = 31464568
431 + 31464137 = 31464568
521 + 31464047 = 31464568
647 + 31463921 = 31464568

Showing the first eight; more decompositions exist.
