Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33528890, here are decompositions:

7 + 33528883 = 33528890
61 + 33528829 = 33528890
67 + 33528823 = 33528890
97 + 33528793 = 33528890
139 + 33528751 = 33528890
151 + 33528739 = 33528890
211 + 33528679 = 33528890
277 + 33528613 = 33528890

Showing the first eight; more decompositions exist.
