Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581786, here are decompositions:

19 + 33581767 = 33581786
79 + 33581707 = 33581786
109 + 33581677 = 33581786
349 + 33581437 = 33581786
373 + 33581413 = 33581786
457 + 33581329 = 33581786
487 + 33581299 = 33581786
499 + 33581287 = 33581786

Showing the first eight; more decompositions exist.
