Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581566, here are decompositions:

173 + 33581393 = 33581566
269 + 33581297 = 33581566
419 + 33581147 = 33581566
443 + 33581123 = 33581566
449 + 33581117 = 33581566
467 + 33581099 = 33581566
479 + 33581087 = 33581566
647 + 33580919 = 33581566

Showing the first eight; more decompositions exist.
