Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33533028, here are decompositions:

7 + 33533021 = 33533028
59 + 33532969 = 33533028
97 + 33532931 = 33533028
101 + 33532927 = 33533028
107 + 33532921 = 33533028
149 + 33532879 = 33533028
157 + 33532871 = 33533028
167 + 33532861 = 33533028

Showing the first eight; more decompositions exist.
