Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518000, here are decompositions:

13 + 33517987 = 33518000
79 + 33517921 = 33518000
97 + 33517903 = 33518000
127 + 33517873 = 33518000
151 + 33517849 = 33518000
349 + 33517651 = 33518000
367 + 33517633 = 33518000
463 + 33517537 = 33518000

Showing the first eight; more decompositions exist.
