Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587500, here are decompositions:

29 + 33587471 = 33587500
83 + 33587417 = 33587500
137 + 33587363 = 33587500
179 + 33587321 = 33587500
197 + 33587303 = 33587500
239 + 33587261 = 33587500
263 + 33587237 = 33587500
281 + 33587219 = 33587500

Showing the first eight; more decompositions exist.
