Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557788, here are decompositions:

59 + 33557729 = 33557788
107 + 33557681 = 33557788
191 + 33557597 = 33557788
227 + 33557561 = 33557788
317 + 33557471 = 33557788
359 + 33557429 = 33557788
389 + 33557399 = 33557788
401 + 33557387 = 33557788

Showing the first eight; more decompositions exist.
