Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477034, here are decompositions:

7 + 31477027 = 31477034
13 + 31477021 = 31477034
103 + 31476931 = 31477034
163 + 31476871 = 31477034
181 + 31476853 = 31477034
307 + 31476727 = 31477034
331 + 31476703 = 31477034
487 + 31476547 = 31477034

Showing the first eight; more decompositions exist.
