Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521806, here are decompositions:

23 + 33521783 = 33521806
47 + 33521759 = 33521806
53 + 33521753 = 33521806
113 + 33521693 = 33521806
257 + 33521549 = 33521806
389 + 33521417 = 33521806
569 + 33521237 = 33521806
587 + 33521219 = 33521806

Showing the first eight; more decompositions exist.
