Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581540, here are decompositions:

19 + 33581521 = 33581540
103 + 33581437 = 33581540
127 + 33581413 = 33581540
211 + 33581329 = 33581540
241 + 33581299 = 33581540
277 + 33581263 = 33581540
283 + 33581257 = 33581540
331 + 33581209 = 33581540

Showing the first eight; more decompositions exist.
