Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533508, here are decompositions:

11 + 31533497 = 31533508
47 + 31533461 = 31533508
59 + 31533449 = 31533508
137 + 31533371 = 31533508
239 + 31533269 = 31533508
317 + 31533191 = 31533508
359 + 31533149 = 31533508
389 + 31533119 = 31533508

Showing the first eight; more decompositions exist.
