Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33611680, here are decompositions:

59 + 33611621 = 33611680
107 + 33611573 = 33611680
191 + 33611489 = 33611680
197 + 33611483 = 33611680
227 + 33611453 = 33611680
233 + 33611447 = 33611680
353 + 33611327 = 33611680
359 + 33611321 = 33611680

Showing the first eight; more decompositions exist.
