Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581238, here are decompositions:

17 + 33581221 = 33581238
29 + 33581209 = 33581238
107 + 33581131 = 33581238
139 + 33581099 = 33581238
151 + 33581087 = 33581238
211 + 33581027 = 33581238
227 + 33581011 = 33581238
281 + 33580957 = 33581238

Showing the first eight; more decompositions exist.
