Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33509240, here are decompositions:

31 + 33509209 = 33509240
67 + 33509173 = 33509240
97 + 33509143 = 33509240
199 + 33509041 = 33509240
211 + 33509029 = 33509240
223 + 33509017 = 33509240
229 + 33509011 = 33509240
337 + 33508903 = 33509240

Showing the first eight; more decompositions exist.
