Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33390, here are decompositions:

13 + 33377 = 33390
31 + 33359 = 33390
37 + 33353 = 33390
41 + 33349 = 33390
43 + 33347 = 33390
47 + 33343 = 33390
59 + 33331 = 33390
61 + 33329 = 33390

Showing the first eight; more decompositions exist.
