Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33535878, here are decompositions:

7 + 33535871 = 33535878
11 + 33535867 = 33535878
31 + 33535847 = 33535878
41 + 33535837 = 33535878
127 + 33535751 = 33535878
149 + 33535729 = 33535878
179 + 33535699 = 33535878
227 + 33535651 = 33535878

Showing the first eight; more decompositions exist.
