Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465816, here are decompositions:

59 + 31465757 = 31465816
89 + 31465727 = 31465816
167 + 31465649 = 31465816
197 + 31465619 = 31465816
269 + 31465547 = 31465816
593 + 31465223 = 31465816
1259 + 31464557 = 31465816
1307 + 31464509 = 31465816

Showing the first eight; more decompositions exist.
