Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521982, here are decompositions:

23 + 33521959 = 33521982
29 + 33521953 = 33521982
61 + 33521921 = 33521982
79 + 33521903 = 33521982
89 + 33521893 = 33521982
139 + 33521843 = 33521982
199 + 33521783 = 33521982
223 + 33521759 = 33521982

Showing the first eight; more decompositions exist.
