Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618040, here are decompositions:

3 + 33618037 = 33618040
11 + 33618029 = 33618040
41 + 33617999 = 33618040
83 + 33617957 = 33618040
107 + 33617933 = 33618040
233 + 33617807 = 33618040
263 + 33617777 = 33618040
293 + 33617747 = 33618040

Showing the first eight; more decompositions exist.
