Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581386, here are decompositions:

5 + 33581381 = 33581386
89 + 33581297 = 33581386
107 + 33581279 = 33581386
239 + 33581147 = 33581386
263 + 33581123 = 33581386
269 + 33581117 = 33581386
359 + 33581027 = 33581386
467 + 33580919 = 33581386

Showing the first eight; more decompositions exist.
