Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33517986, here are decompositions:

43 + 33517943 = 33517986
79 + 33517907 = 33517986
83 + 33517903 = 33517986
107 + 33517879 = 33517986
113 + 33517873 = 33517986
137 + 33517849 = 33517986
193 + 33517793 = 33517986
223 + 33517763 = 33517986

Showing the first eight; more decompositions exist.
