Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518180, here are decompositions:

43 + 33518137 = 33518180
61 + 33518119 = 33518180
151 + 33518029 = 33518180
193 + 33517987 = 33518180
277 + 33517903 = 33518180
307 + 33517873 = 33518180
331 + 33517849 = 33518180
433 + 33517747 = 33518180

Showing the first eight; more decompositions exist.
