Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505180, here are decompositions:

3 + 33505177 = 33505180
17 + 33505163 = 33505180
113 + 33505067 = 33505180
131 + 33505049 = 33505180
173 + 33505007 = 33505180
179 + 33505001 = 33505180
197 + 33504983 = 33505180
239 + 33504941 = 33505180

Showing the first eight; more decompositions exist.
