Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521810, here are decompositions:

13 + 33521797 = 33521810
79 + 33521731 = 33521810
97 + 33521713 = 33521810
109 + 33521701 = 33521810
163 + 33521647 = 33521810
181 + 33521629 = 33521810
271 + 33521539 = 33521810
349 + 33521461 = 33521810

Showing the first eight; more decompositions exist.
