Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464556, here are decompositions:

47 + 31464509 = 31464556
113 + 31464443 = 31464556
197 + 31464359 = 31464556
419 + 31464137 = 31464556
509 + 31464047 = 31464556
593 + 31463963 = 31464556
647 + 31463909 = 31464556
659 + 31463897 = 31464556

Showing the first eight; more decompositions exist.
