Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513856, here are decompositions:

17 + 33513839 = 33513856
59 + 33513797 = 33513856
149 + 33513707 = 33513856
197 + 33513659 = 33513856
227 + 33513629 = 33513856
317 + 33513539 = 33513856
347 + 33513509 = 33513856
353 + 33513503 = 33513856

Showing the first eight; more decompositions exist.
