Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581560, here are decompositions:

149 + 33581411 = 33581560
167 + 33581393 = 33581560
179 + 33581381 = 33581560
239 + 33581321 = 33581560
263 + 33581297 = 33581560
269 + 33581291 = 33581560
281 + 33581279 = 33581560
293 + 33581267 = 33581560

Showing the first eight; more decompositions exist.
