Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33609980, here are decompositions:

67 + 33609913 = 33609980
73 + 33609907 = 33609980
163 + 33609817 = 33609980
193 + 33609787 = 33609980
211 + 33609769 = 33609980
223 + 33609757 = 33609980
331 + 33609649 = 33609980
373 + 33609607 = 33609980

Showing the first eight; more decompositions exist.
