Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620466, here are decompositions:

23 + 31620443 = 31620466
107 + 31620359 = 31620466
149 + 31620317 = 31620466
167 + 31620299 = 31620466
197 + 31620269 = 31620466
257 + 31620209 = 31620466
263 + 31620203 = 31620466
359 + 31620107 = 31620466

Showing the first eight; more decompositions exist.
