Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505120, here are decompositions:

3 + 33505117 = 33505120
17 + 33505103 = 33505120
53 + 33505067 = 33505120
71 + 33505049 = 33505120
113 + 33505007 = 33505120
137 + 33504983 = 33505120
179 + 33504941 = 33505120
191 + 33504929 = 33505120

Showing the first eight; more decompositions exist.
