Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581398, here are decompositions:

5 + 33581393 = 33581398
17 + 33581381 = 33581398
47 + 33581351 = 33581398
101 + 33581297 = 33581398
107 + 33581291 = 33581398
131 + 33581267 = 33581398
251 + 33581147 = 33581398
281 + 33581117 = 33581398

Showing the first eight; more decompositions exist.
