Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533064, here are decompositions:

83 + 31532981 = 31533064
191 + 31532873 = 31533064
197 + 31532867 = 31533064
467 + 31532597 = 31533064
491 + 31532573 = 31533064
557 + 31532507 = 31533064
587 + 31532477 = 31533064
947 + 31532117 = 31533064

Showing the first eight; more decompositions exist.
