Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33611778, here are decompositions:

29 + 33611749 = 33611778
71 + 33611707 = 33611778
149 + 33611629 = 33611778
157 + 33611621 = 33611778
241 + 33611537 = 33611778
281 + 33611497 = 33611778
311 + 33611467 = 33611778
331 + 33611447 = 33611778

Showing the first eight; more decompositions exist.
