Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33508520, here are decompositions:

13 + 33508507 = 33508520
103 + 33508417 = 33508520
181 + 33508339 = 33508520
229 + 33508291 = 33508520
307 + 33508213 = 33508520
337 + 33508183 = 33508520
373 + 33508147 = 33508520
607 + 33507913 = 33508520

Showing the first eight; more decompositions exist.
