Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587512, here are decompositions:

3 + 33587509 = 33587512
5 + 33587507 = 33587512
41 + 33587471 = 33587512
149 + 33587363 = 33587512
173 + 33587339 = 33587512
191 + 33587321 = 33587512
251 + 33587261 = 33587512
293 + 33587219 = 33587512

Showing the first eight; more decompositions exist.
