Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477374, here are decompositions:

23 + 31477351 = 31477374
53 + 31477321 = 31477374
73 + 31477301 = 31477374
83 + 31477291 = 31477374
167 + 31477207 = 31477374
193 + 31477181 = 31477374
211 + 31477163 = 31477374
233 + 31477141 = 31477374

Showing the first eight; more decompositions exist.
