Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33543918, here are decompositions:

17 + 33543901 = 33543918
19 + 33543899 = 33543918
41 + 33543877 = 33543918
61 + 33543857 = 33543918
127 + 33543791 = 33543918
157 + 33543761 = 33543918
229 + 33543689 = 33543918
257 + 33543661 = 33543918

Showing the first eight; more decompositions exist.
