Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477308, here are decompositions:

7 + 31477301 = 31477308
17 + 31477291 = 31477308
19 + 31477289 = 31477308
101 + 31477207 = 31477308
127 + 31477181 = 31477308
167 + 31477141 = 31477308
197 + 31477111 = 31477308
229 + 31477079 = 31477308

Showing the first eight; more decompositions exist.
