Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33018, here are decompositions:

5 + 33013 = 33018
19 + 32999 = 33018
31 + 32987 = 33018
47 + 32971 = 33018
61 + 32957 = 33018
79 + 32939 = 33018
101 + 32917 = 33018
107 + 32911 = 33018

Showing the first eight; more decompositions exist.
