Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464126, here are decompositions:

47 + 31464079 = 31464126
59 + 31464067 = 31464126
79 + 31464047 = 31464126
163 + 31463963 = 31464126
167 + 31463959 = 31464126
229 + 31463897 = 31464126
233 + 31463893 = 31464126
269 + 31463857 = 31464126

Showing the first eight; more decompositions exist.
