Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581666, here are decompositions:

67 + 33581599 = 33581666
229 + 33581437 = 33581666
337 + 33581329 = 33581666
367 + 33581299 = 33581666
379 + 33581287 = 33581666
409 + 33581257 = 33581666
457 + 33581209 = 33581666
673 + 33580993 = 33581666

Showing the first eight; more decompositions exist.
