Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477342, here are decompositions:

41 + 31477301 = 31477342
53 + 31477289 = 31477342
179 + 31477163 = 31477342
263 + 31477079 = 31477342
383 + 31476959 = 31477342
461 + 31476881 = 31477342
521 + 31476821 = 31477342
599 + 31476743 = 31477342

Showing the first eight; more decompositions exist.
