Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587240, here are decompositions:

3 + 33587237 = 33587240
7 + 33587233 = 33587240
31 + 33587209 = 33587240
67 + 33587173 = 33587240
79 + 33587161 = 33587240
97 + 33587143 = 33587240
151 + 33587089 = 33587240
229 + 33587011 = 33587240

Showing the first eight; more decompositions exist.
