Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33497408, here are decompositions:

67 + 33497341 = 33497408
97 + 33497311 = 33497408
127 + 33497281 = 33497408
151 + 33497257 = 33497408
157 + 33497251 = 33497408
337 + 33497071 = 33497408
379 + 33497029 = 33497408
487 + 33496921 = 33497408

Showing the first eight; more decompositions exist.
