Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33512940, here are decompositions:

11 + 33512929 = 33512940
59 + 33512881 = 33512940
67 + 33512873 = 33512940
101 + 33512839 = 33512940
103 + 33512837 = 33512940
157 + 33512783 = 33512940
193 + 33512747 = 33512940
269 + 33512671 = 33512940

Showing the first eight; more decompositions exist.
