Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581530, here are decompositions:

89 + 33581441 = 33581530
137 + 33581393 = 33581530
149 + 33581381 = 33581530
179 + 33581351 = 33581530
233 + 33581297 = 33581530
239 + 33581291 = 33581530
251 + 33581279 = 33581530
263 + 33581267 = 33581530

Showing the first eight; more decompositions exist.
