Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581508, here are decompositions:

17 + 33581491 = 33581508
67 + 33581441 = 33581508
71 + 33581437 = 33581508
97 + 33581411 = 33581508
127 + 33581381 = 33581508
157 + 33581351 = 33581508
179 + 33581329 = 33581508
211 + 33581297 = 33581508

Showing the first eight; more decompositions exist.
