Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505128, here are decompositions:

5 + 33505123 = 33505128
11 + 33505117 = 33505128
61 + 33505067 = 33505128
71 + 33505057 = 33505128
79 + 33505049 = 33505128
89 + 33505039 = 33505128
127 + 33505001 = 33505128
199 + 33504929 = 33505128

Showing the first eight; more decompositions exist.
