Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471716, here are decompositions:

5 + 31471711 = 31471716
13 + 31471703 = 31471716
19 + 31471697 = 31471716
53 + 31471663 = 31471716
79 + 31471637 = 31471716
83 + 31471633 = 31471716
137 + 31471579 = 31471716
139 + 31471577 = 31471716

Showing the first eight; more decompositions exist.
