Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33506800, here are decompositions:

3 + 33506797 = 33506800
23 + 33506777 = 33506800
59 + 33506741 = 33506800
137 + 33506663 = 33506800
227 + 33506573 = 33506800
251 + 33506549 = 33506800
401 + 33506399 = 33506800
479 + 33506321 = 33506800

Showing the first eight; more decompositions exist.
