Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581480, here are decompositions:

43 + 33581437 = 33581480
67 + 33581413 = 33581480
151 + 33581329 = 33581480
181 + 33581299 = 33581480
193 + 33581287 = 33581480
199 + 33581281 = 33581480
223 + 33581257 = 33581480
271 + 33581209 = 33581480

Showing the first eight; more decompositions exist.
