Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447306, here are decompositions:

5 + 31447301 = 31447306
53 + 31447253 = 31447306
89 + 31447217 = 31447306
173 + 31447133 = 31447306
227 + 31447079 = 31447306
263 + 31447043 = 31447306
353 + 31446953 = 31447306
389 + 31446917 = 31447306

Showing the first eight; more decompositions exist.
