Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33611978, here are decompositions:

19 + 33611959 = 33611978
157 + 33611821 = 33611978
181 + 33611797 = 33611978
229 + 33611749 = 33611978
271 + 33611707 = 33611978
277 + 33611701 = 33611978
349 + 33611629 = 33611978
571 + 33611407 = 33611978

Showing the first eight; more decompositions exist.
