Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518500, here are decompositions:

3 + 33518497 = 33518500
47 + 33518453 = 33518500
83 + 33518417 = 33518500
107 + 33518393 = 33518500
149 + 33518351 = 33518500
167 + 33518333 = 33518500
173 + 33518327 = 33518500
227 + 33518273 = 33518500

Showing the first eight; more decompositions exist.
