Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518072, here are decompositions:

43 + 33518029 = 33518072
61 + 33518011 = 33518072
151 + 33517921 = 33518072
193 + 33517879 = 33518072
199 + 33517873 = 33518072
223 + 33517849 = 33518072
331 + 33517741 = 33518072
421 + 33517651 = 33518072

Showing the first eight; more decompositions exist.
