Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518040, here are decompositions:

11 + 33518029 = 33518040
19 + 33518021 = 33518040
29 + 33518011 = 33518040
53 + 33517987 = 33518040
97 + 33517943 = 33518040
137 + 33517903 = 33518040
139 + 33517901 = 33518040
167 + 33517873 = 33518040

Showing the first eight; more decompositions exist.
