Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533016, here are decompositions:

3 + 31533013 = 31533016
17 + 31532999 = 31533016
149 + 31532867 = 31533016
239 + 31532777 = 31533016
419 + 31532597 = 31533016
443 + 31532573 = 31533016
509 + 31532507 = 31533016
587 + 31532429 = 31533016

Showing the first eight; more decompositions exist.
