Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33511660, here are decompositions:

47 + 33511613 = 33511660
59 + 33511601 = 33511660
89 + 33511571 = 33511660
113 + 33511547 = 33511660
173 + 33511487 = 33511660
251 + 33511409 = 33511660
263 + 33511397 = 33511660
293 + 33511367 = 33511660

Showing the first eight; more decompositions exist.
