Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33585180, here are decompositions:

7 + 33585173 = 33585180
17 + 33585163 = 33585180
37 + 33585143 = 33585180
47 + 33585133 = 33585180
53 + 33585127 = 33585180
67 + 33585113 = 33585180
103 + 33585077 = 33585180
107 + 33585073 = 33585180

Showing the first eight; more decompositions exist.
