Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477318, here are decompositions:

17 + 31477301 = 31477318
29 + 31477289 = 31477318
137 + 31477181 = 31477318
239 + 31477079 = 31477318
251 + 31477067 = 31477318
359 + 31476959 = 31477318
401 + 31476917 = 31477318
809 + 31476509 = 31477318

Showing the first eight; more decompositions exist.
