Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33528940, here are decompositions:

101 + 33528839 = 33528940
173 + 33528767 = 33528940
233 + 33528707 = 33528940
251 + 33528689 = 33528940
281 + 33528659 = 33528940
311 + 33528629 = 33528940
443 + 33528497 = 33528940
449 + 33528491 = 33528940

Showing the first eight; more decompositions exist.
