Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33526728, here are decompositions:

5 + 33526723 = 33526728
61 + 33526667 = 33526728
71 + 33526657 = 33526728
139 + 33526589 = 33526728
149 + 33526579 = 33526728
211 + 33526517 = 33526728
227 + 33526501 = 33526728
241 + 33526487 = 33526728

Showing the first eight; more decompositions exist.
