Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464016, here are decompositions:

53 + 31463963 = 31464016
107 + 31463909 = 31464016
137 + 31463879 = 31464016
167 + 31463849 = 31464016
173 + 31463843 = 31464016
257 + 31463759 = 31464016
509 + 31463507 = 31464016
557 + 31463459 = 31464016

Showing the first eight; more decompositions exist.
