Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485466, here are decompositions:

17 + 31485449 = 31485466
59 + 31485407 = 31485466
83 + 31485383 = 31485466
107 + 31485359 = 31485466
113 + 31485353 = 31485466
197 + 31485269 = 31485466
269 + 31485197 = 31485466
359 + 31485107 = 31485466

Showing the first eight; more decompositions exist.
