Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485410, here are decompositions:

3 + 31485407 = 31485410
13 + 31485397 = 31485410
31 + 31485379 = 31485410
97 + 31485313 = 31485410
109 + 31485301 = 31485410
127 + 31485283 = 31485410
163 + 31485247 = 31485410
331 + 31485079 = 31485410

Showing the first eight; more decompositions exist.
