Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557728, here are decompositions:

47 + 33557681 = 33557728
101 + 33557627 = 33557728
131 + 33557597 = 33557728
167 + 33557561 = 33557728
257 + 33557471 = 33557728
311 + 33557417 = 33557728
317 + 33557411 = 33557728
389 + 33557339 = 33557728

Showing the first eight; more decompositions exist.
