Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581328, here are decompositions:

7 + 33581321 = 33581328
29 + 33581299 = 33581328
31 + 33581297 = 33581328
37 + 33581291 = 33581328
41 + 33581287 = 33581328
47 + 33581281 = 33581328
61 + 33581267 = 33581328
71 + 33581257 = 33581328

Showing the first eight; more decompositions exist.
