Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477344, here are decompositions:

23 + 31477321 = 31477344
43 + 31477301 = 31477344
53 + 31477291 = 31477344
131 + 31477213 = 31477344
137 + 31477207 = 31477344
163 + 31477181 = 31477344
181 + 31477163 = 31477344
233 + 31477111 = 31477344

Showing the first eight; more decompositions exist.
