Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477260, here are decompositions:

47 + 31477213 = 31477260
53 + 31477207 = 31477260
79 + 31477181 = 31477260
97 + 31477163 = 31477260
149 + 31477111 = 31477260
181 + 31477079 = 31477260
193 + 31477067 = 31477260
197 + 31477063 = 31477260

Showing the first eight; more decompositions exist.
