Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587280, here are decompositions:

17 + 33587263 = 33587280
19 + 33587261 = 33587280
29 + 33587251 = 33587280
43 + 33587237 = 33587280
47 + 33587233 = 33587280
61 + 33587219 = 33587280
71 + 33587209 = 33587280
107 + 33587173 = 33587280

Showing the first eight; more decompositions exist.
