Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33511986, here are decompositions:

7 + 33511979 = 33511986
19 + 33511967 = 33511986
23 + 33511963 = 33511986
37 + 33511949 = 33511986
47 + 33511939 = 33511986
97 + 33511889 = 33511986
197 + 33511789 = 33511986
229 + 33511757 = 33511986

Showing the first eight; more decompositions exist.
