Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505940, here are decompositions:

37 + 33505903 = 33505940
73 + 33505867 = 33505940
151 + 33505789 = 33505940
163 + 33505777 = 33505940
277 + 33505663 = 33505940
367 + 33505573 = 33505940
373 + 33505567 = 33505940
397 + 33505543 = 33505940

Showing the first eight; more decompositions exist.
