Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518142, here are decompositions:

5 + 33518137 = 33518142
11 + 33518131 = 33518142
23 + 33518119 = 33518142
61 + 33518081 = 33518142
113 + 33518029 = 33518142
131 + 33518011 = 33518142
199 + 33517943 = 33518142
239 + 33517903 = 33518142

Showing the first eight; more decompositions exist.
