Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581986, here are decompositions:

29 + 33581957 = 33581986
59 + 33581927 = 33581986
149 + 33581837 = 33581986
167 + 33581819 = 33581986
173 + 33581813 = 33581986
293 + 33581693 = 33581986
593 + 33581393 = 33581986
719 + 33581267 = 33581986

Showing the first eight; more decompositions exist.
