Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581450, here are decompositions:

13 + 33581437 = 33581450
37 + 33581413 = 33581450
151 + 33581299 = 33581450
163 + 33581287 = 33581450
193 + 33581257 = 33581450
229 + 33581221 = 33581450
241 + 33581209 = 33581450
439 + 33581011 = 33581450

Showing the first eight; more decompositions exist.
