Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581660, here are decompositions:

43 + 33581617 = 33581660
61 + 33581599 = 33581660
139 + 33581521 = 33581660
223 + 33581437 = 33581660
331 + 33581329 = 33581660
373 + 33581287 = 33581660
379 + 33581281 = 33581660
397 + 33581263 = 33581660

Showing the first eight; more decompositions exist.
