Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471266, here are decompositions:

53 + 31471213 = 31471266
59 + 31471207 = 31471266
157 + 31471109 = 31471266
173 + 31471093 = 31471266
223 + 31471043 = 31471266
269 + 31470997 = 31471266
313 + 31470953 = 31471266
349 + 31470917 = 31471266

Showing the first eight; more decompositions exist.
