Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33617986, here are decompositions:

23 + 33617963 = 33617986
29 + 33617957 = 33617986
53 + 33617933 = 33617986
167 + 33617819 = 33617986
179 + 33617807 = 33617986
239 + 33617747 = 33617986
257 + 33617729 = 33617986
383 + 33617603 = 33617986

Showing the first eight; more decompositions exist.
