Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521928, here are decompositions:

7 + 33521921 = 33521928
67 + 33521861 = 33521928
101 + 33521827 = 33521928
107 + 33521821 = 33521928
131 + 33521797 = 33521928
197 + 33521731 = 33521928
199 + 33521729 = 33521928
227 + 33521701 = 33521928

Showing the first eight; more decompositions exist.
