Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477302, here are decompositions:

11 + 31477291 = 31477302
13 + 31477289 = 31477302
89 + 31477213 = 31477302
139 + 31477163 = 31477302
191 + 31477111 = 31477302
223 + 31477079 = 31477302
239 + 31477063 = 31477302
251 + 31477051 = 31477302

Showing the first eight; more decompositions exist.
