Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471306, here are decompositions:

17 + 31471289 = 31471306
89 + 31471217 = 31471306
197 + 31471109 = 31471306
227 + 31471079 = 31471306
263 + 31471043 = 31471306
353 + 31470953 = 31471306
389 + 31470917 = 31471306
443 + 31470863 = 31471306

Showing the first eight; more decompositions exist.
