Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33500728, here are decompositions:

5 + 33500723 = 33500728
29 + 33500699 = 33500728
179 + 33500549 = 33500728
227 + 33500501 = 33500728
269 + 33500459 = 33500728
281 + 33500447 = 33500728
311 + 33500417 = 33500728
431 + 33500297 = 33500728

Showing the first eight; more decompositions exist.
