Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33497918, here are decompositions:

7 + 33497911 = 33497918
499 + 33497419 = 33497918
577 + 33497341 = 33497918
607 + 33497311 = 33497918
661 + 33497257 = 33497918
997 + 33496921 = 33497918
1009 + 33496909 = 33497918
1069 + 33496849 = 33497918

Showing the first eight; more decompositions exist.
