Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487178, here are decompositions:

31 + 33487147 = 33487178
61 + 33487117 = 33487178
97 + 33487081 = 33487178
157 + 33487021 = 33487178
181 + 33486997 = 33487178
331 + 33486847 = 33487178
337 + 33486841 = 33487178
349 + 33486829 = 33487178

Showing the first eight; more decompositions exist.
