Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581668, here are decompositions:

47 + 33581621 = 33581668
227 + 33581441 = 33581668
257 + 33581411 = 33581668
317 + 33581351 = 33581668
347 + 33581321 = 33581668
389 + 33581279 = 33581668
401 + 33581267 = 33581668
521 + 33581147 = 33581668

Showing the first eight; more decompositions exist.
