Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533412, here are decompositions:

3 + 31533409 = 31533412
23 + 31533389 = 31533412
41 + 31533371 = 31533412
263 + 31533149 = 31533412
269 + 31533143 = 31533412
293 + 31533119 = 31533412
311 + 31533101 = 31533412
431 + 31532981 = 31533412

Showing the first eight; more decompositions exist.
