Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518240, here are decompositions:

31 + 33518209 = 33518240
103 + 33518137 = 33518240
109 + 33518131 = 33518240
193 + 33518047 = 33518240
211 + 33518029 = 33518240
229 + 33518011 = 33518240
337 + 33517903 = 33518240
367 + 33517873 = 33518240

Showing the first eight; more decompositions exist.
