Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521700, here are decompositions:

7 + 33521693 = 33521700
11 + 33521689 = 33521700
53 + 33521647 = 33521700
71 + 33521629 = 33521700
151 + 33521549 = 33521700
229 + 33521471 = 33521700
239 + 33521461 = 33521700
263 + 33521437 = 33521700

Showing the first eight; more decompositions exist.
