Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477312, here are decompositions:

11 + 31477301 = 31477312
23 + 31477289 = 31477312
131 + 31477181 = 31477312
149 + 31477163 = 31477312
233 + 31477079 = 31477312
353 + 31476959 = 31477312
431 + 31476881 = 31477312
491 + 31476821 = 31477312

Showing the first eight; more decompositions exist.
