Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477654, here are decompositions:

71 + 31477583 = 31477654
83 + 31477571 = 31477654
101 + 31477553 = 31477654
227 + 31477427 = 31477654
353 + 31477301 = 31477654
491 + 31477163 = 31477654
587 + 31477067 = 31477654
773 + 31476881 = 31477654

Showing the first eight; more decompositions exist.
