Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587628, here are decompositions:

47 + 33587581 = 33587628
71 + 33587557 = 33587628
79 + 33587549 = 33587628
149 + 33587479 = 33587628
157 + 33587471 = 33587628
211 + 33587417 = 33587628
227 + 33587401 = 33587628
257 + 33587371 = 33587628

Showing the first eight; more decompositions exist.
