Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581886, here are decompositions:

17 + 33581869 = 33581886
29 + 33581857 = 33581886
67 + 33581819 = 33581886
73 + 33581813 = 33581886
179 + 33581707 = 33581886
193 + 33581693 = 33581886
199 + 33581687 = 33581886
269 + 33581617 = 33581886

Showing the first eight; more decompositions exist.
