Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33509186, here are decompositions:

13 + 33509173 = 33509186
37 + 33509149 = 33509186
43 + 33509143 = 33509186
157 + 33509029 = 33509186
199 + 33508987 = 33509186
283 + 33508903 = 33509186
379 + 33508807 = 33509186
433 + 33508753 = 33509186

Showing the first eight; more decompositions exist.
