Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33528628, here are decompositions:

11 + 33528617 = 33528628
101 + 33528527 = 33528628
131 + 33528497 = 33528628
137 + 33528491 = 33528628
149 + 33528479 = 33528628
251 + 33528377 = 33528628
359 + 33528269 = 33528628
461 + 33528167 = 33528628

Showing the first eight; more decompositions exist.
