Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531330, here are decompositions:

11 + 33531319 = 33531330
31 + 33531299 = 33531330
47 + 33531283 = 33531330
61 + 33531269 = 33531330
83 + 33531247 = 33531330
97 + 33531233 = 33531330
101 + 33531229 = 33531330
163 + 33531167 = 33531330

Showing the first eight; more decompositions exist.
