Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33508380, here are decompositions:

19 + 33508361 = 33508380
41 + 33508339 = 33508380
47 + 33508333 = 33508380
79 + 33508301 = 33508380
89 + 33508291 = 33508380
167 + 33508213 = 33508380
197 + 33508183 = 33508380
233 + 33508147 = 33508380

Showing the first eight; more decompositions exist.
