Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477514, here are decompositions:

7 + 31477507 = 31477514
31 + 31477483 = 31477514
67 + 31477447 = 31477514
163 + 31477351 = 31477514
193 + 31477321 = 31477514
223 + 31477291 = 31477514
307 + 31477207 = 31477514
373 + 31477141 = 31477514

Showing the first eight; more decompositions exist.
