Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477656, here are decompositions:

53 + 31477603 = 31477656
73 + 31477583 = 31477656
79 + 31477577 = 31477656
103 + 31477553 = 31477656
107 + 31477549 = 31477656
113 + 31477543 = 31477656
149 + 31477507 = 31477656
173 + 31477483 = 31477656

Showing the first eight; more decompositions exist.
