Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33611780, here are decompositions:

31 + 33611749 = 33611780
67 + 33611713 = 33611780
73 + 33611707 = 33611780
79 + 33611701 = 33611780
127 + 33611653 = 33611780
151 + 33611629 = 33611780
283 + 33611497 = 33611780
313 + 33611467 = 33611780

Showing the first eight; more decompositions exist.
