Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464272, here are decompositions:

3 + 31464269 = 31464272
79 + 31464193 = 31464272
193 + 31464079 = 31464272
211 + 31464061 = 31464272
241 + 31464031 = 31464272
271 + 31464001 = 31464272
313 + 31463959 = 31464272
331 + 31463941 = 31464272

Showing the first eight; more decompositions exist.
