Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477448, here are decompositions:

19 + 31477429 = 31477448
97 + 31477351 = 31477448
127 + 31477321 = 31477448
157 + 31477291 = 31477448
241 + 31477207 = 31477448
307 + 31477141 = 31477448
337 + 31477111 = 31477448
349 + 31477099 = 31477448

Showing the first eight; more decompositions exist.
