Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477254, here are decompositions:

41 + 31477213 = 31477254
47 + 31477207 = 31477254
73 + 31477181 = 31477254
113 + 31477141 = 31477254
191 + 31477063 = 31477254
197 + 31477057 = 31477254
227 + 31477027 = 31477254
233 + 31477021 = 31477254

Showing the first eight; more decompositions exist.
