Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471674, here are decompositions:

7 + 31471667 = 31471674
11 + 31471663 = 31471674
37 + 31471637 = 31471674
41 + 31471633 = 31471674
53 + 31471621 = 31471674
83 + 31471591 = 31471674
97 + 31471577 = 31471674
151 + 31471523 = 31471674

Showing the first eight; more decompositions exist.
