Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587388, here are decompositions:

17 + 33587371 = 33587388
31 + 33587357 = 33587388
41 + 33587347 = 33587388
67 + 33587321 = 33587388
101 + 33587287 = 33587388
127 + 33587261 = 33587388
137 + 33587251 = 33587388
151 + 33587237 = 33587388

Showing the first eight; more decompositions exist.
