Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485014, here are decompositions:

13 + 31485001 = 31485014
73 + 31484941 = 31485014
103 + 31484911 = 31485014
151 + 31484863 = 31485014
193 + 31484821 = 31485014
367 + 31484647 = 31485014
397 + 31484617 = 31485014
601 + 31484413 = 31485014

Showing the first eight; more decompositions exist.
