Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533420, here are decompositions:

7 + 31533413 = 31533420
11 + 31533409 = 31533420
31 + 31533389 = 31533420
41 + 31533379 = 31533420
151 + 31533269 = 31533420
211 + 31533209 = 31533420
229 + 31533191 = 31533420
271 + 31533149 = 31533420

Showing the first eight; more decompositions exist.
