Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33619986, here are decompositions:

5 + 33619981 = 33619986
7 + 33619979 = 33619986
13 + 33619973 = 33619986
67 + 33619919 = 33619986
139 + 33619847 = 33619986
223 + 33619763 = 33619986
229 + 33619757 = 33619986
233 + 33619753 = 33619986

Showing the first eight; more decompositions exist.
