Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33497040, here are decompositions:

11 + 33497029 = 33497040
37 + 33497003 = 33497040
61 + 33496979 = 33497040
131 + 33496909 = 33497040
179 + 33496861 = 33497040
191 + 33496849 = 33497040
373 + 33496667 = 33497040
389 + 33496651 = 33497040

Showing the first eight; more decompositions exist.
