Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466536, here are decompositions:

149 + 31466387 = 31466536
557 + 31465979 = 31466536
809 + 31465727 = 31466536
839 + 31465697 = 31466536
863 + 31465673 = 31466536
887 + 31465649 = 31466536
1709 + 31464827 = 31466536
1979 + 31464557 = 31466536

Showing the first eight; more decompositions exist.
