Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33528778, here are decompositions:

11 + 33528767 = 33528778
47 + 33528731 = 33528778
71 + 33528707 = 33528778
89 + 33528689 = 33528778
149 + 33528629 = 33528778
251 + 33528527 = 33528778
281 + 33528497 = 33528778
401 + 33528377 = 33528778

Showing the first eight; more decompositions exist.
