Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581866, here are decompositions:

5 + 33581861 = 33581866
29 + 33581837 = 33581866
47 + 33581819 = 33581866
53 + 33581813 = 33581866
173 + 33581693 = 33581866
179 + 33581687 = 33581866
293 + 33581573 = 33581866
569 + 33581297 = 33581866

Showing the first eight; more decompositions exist.
