Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485026, here are decompositions:

3 + 31485023 = 31485026
7 + 31485019 = 31485026
37 + 31484989 = 31485026
163 + 31484863 = 31485026
229 + 31484797 = 31485026
379 + 31484647 = 31485026
409 + 31484617 = 31485026
457 + 31484569 = 31485026

Showing the first eight; more decompositions exist.
