Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33508186, here are decompositions:

3 + 33508183 = 33508186
59 + 33508127 = 33508186
83 + 33508103 = 33508186
167 + 33508019 = 33508186
197 + 33507989 = 33508186
263 + 33507923 = 33508186
293 + 33507893 = 33508186
389 + 33507797 = 33508186

Showing the first eight; more decompositions exist.
