Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521906, here are decompositions:

3 + 33521903 = 33521906
13 + 33521893 = 33521906
43 + 33521863 = 33521906
79 + 33521827 = 33521906
109 + 33521797 = 33521906
193 + 33521713 = 33521906
277 + 33521629 = 33521906
283 + 33521623 = 33521906

Showing the first eight; more decompositions exist.
