Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505278, here are decompositions:

17 + 33505261 = 33505278
31 + 33505247 = 33505278
67 + 33505211 = 33505278
101 + 33505177 = 33505278
211 + 33505067 = 33505278
227 + 33505051 = 33505278
229 + 33505049 = 33505278
239 + 33505039 = 33505278

Showing the first eight; more decompositions exist.
