Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33528142, here are decompositions:

5 + 33528137 = 33528142
101 + 33528041 = 33528142
149 + 33527993 = 33528142
173 + 33527969 = 33528142
233 + 33527909 = 33528142
359 + 33527783 = 33528142
443 + 33527699 = 33528142
449 + 33527693 = 33528142

Showing the first eight; more decompositions exist.
