Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464228, here are decompositions:

41 + 31464187 = 31464228
79 + 31464149 = 31464228
149 + 31464079 = 31464228
167 + 31464061 = 31464228
181 + 31464047 = 31464228
197 + 31464031 = 31464228
227 + 31464001 = 31464228
269 + 31463959 = 31464228

Showing the first eight; more decompositions exist.
