Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485062, here are decompositions:

3 + 31485059 = 31485062
13 + 31485049 = 31485062
31 + 31485031 = 31485062
43 + 31485019 = 31485062
61 + 31485001 = 31485062
73 + 31484989 = 31485062
151 + 31484911 = 31485062
199 + 31484863 = 31485062

Showing the first eight; more decompositions exist.
