Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581638, here are decompositions:

17 + 33581621 = 33581638
197 + 33581441 = 33581638
227 + 33581411 = 33581638
257 + 33581381 = 33581638
317 + 33581321 = 33581638
347 + 33581291 = 33581638
359 + 33581279 = 33581638
491 + 33581147 = 33581638

Showing the first eight; more decompositions exist.
