Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618018, here are decompositions:

11 + 33618007 = 33618018
17 + 33618001 = 33618018
19 + 33617999 = 33618018
47 + 33617971 = 33618018
61 + 33617957 = 33618018
97 + 33617921 = 33618018
167 + 33617851 = 33618018
199 + 33617819 = 33618018

Showing the first eight; more decompositions exist.
