Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33486978, here are decompositions:

37 + 33486941 = 33486978
61 + 33486917 = 33486978
131 + 33486847 = 33486978
137 + 33486841 = 33486978
149 + 33486829 = 33486978
179 + 33486799 = 33486978
211 + 33486767 = 33486978
227 + 33486751 = 33486978

Showing the first eight; more decompositions exist.
