Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33420, here are decompositions:

7 + 33413 = 33420
11 + 33409 = 33420
17 + 33403 = 33420
29 + 33391 = 33420
43 + 33377 = 33420
61 + 33359 = 33420
67 + 33353 = 33420
71 + 33349 = 33420

Showing the first eight; more decompositions exist.
