Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464212, here are decompositions:

19 + 31464193 = 31464212
151 + 31464061 = 31464212
181 + 31464031 = 31464212
211 + 31464001 = 31464212
271 + 31463941 = 31464212
433 + 31463779 = 31464212
499 + 31463713 = 31464212
523 + 31463689 = 31464212

Showing the first eight; more decompositions exist.
