Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533466, here are decompositions:

5 + 31533461 = 31533466
17 + 31533449 = 31533466
53 + 31533413 = 31533466
197 + 31533269 = 31533466
257 + 31533209 = 31533466
317 + 31533149 = 31533466
347 + 31533119 = 31533466
467 + 31532999 = 31533466

Showing the first eight; more decompositions exist.
