Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587428, here are decompositions:

11 + 33587417 = 33587428
71 + 33587357 = 33587428
89 + 33587339 = 33587428
107 + 33587321 = 33587428
167 + 33587261 = 33587428
191 + 33587237 = 33587428
317 + 33587111 = 33587428
389 + 33587039 = 33587428

Showing the first eight; more decompositions exist.
