Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542728, here are decompositions:

5 + 33542723 = 33542728
17 + 33542711 = 33542728
239 + 33542489 = 33542728
251 + 33542477 = 33542728
389 + 33542339 = 33542728
431 + 33542297 = 33542728
467 + 33542261 = 33542728
491 + 33542237 = 33542728

Showing the first eight; more decompositions exist.
