Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505140, here are decompositions:

17 + 33505123 = 33505140
23 + 33505117 = 33505140
37 + 33505103 = 33505140
73 + 33505067 = 33505140
83 + 33505057 = 33505140
89 + 33505051 = 33505140
101 + 33505039 = 33505140
131 + 33505009 = 33505140

Showing the first eight; more decompositions exist.
