Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518320, here are decompositions:

23 + 33518297 = 33518320
47 + 33518273 = 33518320
53 + 33518267 = 33518320
107 + 33518213 = 33518320
179 + 33518141 = 33518320
239 + 33518081 = 33518320
419 + 33517901 = 33518320
449 + 33517871 = 33518320

Showing the first eight; more decompositions exist.
