Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587440, here are decompositions:

23 + 33587417 = 33587440
83 + 33587357 = 33587440
101 + 33587339 = 33587440
137 + 33587303 = 33587440
179 + 33587261 = 33587440
389 + 33587051 = 33587440
401 + 33587039 = 33587440
443 + 33586997 = 33587440

Showing the first eight; more decompositions exist.
