Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33543218, here are decompositions:

19 + 33543199 = 33543218
31 + 33543187 = 33543218
61 + 33543157 = 33543218
139 + 33543079 = 33543218
151 + 33543067 = 33543218
157 + 33543061 = 33543218
199 + 33543019 = 33543218
367 + 33542851 = 33543218

Showing the first eight; more decompositions exist.
