Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518286, here are decompositions:

13 + 33518273 = 33518286
17 + 33518269 = 33518286
19 + 33518267 = 33518286
47 + 33518239 = 33518286
73 + 33518213 = 33518286
149 + 33518137 = 33518286
167 + 33518119 = 33518286
239 + 33518047 = 33518286

Showing the first eight; more decompositions exist.
