Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33617280, here are decompositions:

17 + 33617263 = 33617280
19 + 33617261 = 33617280
41 + 33617239 = 33617280
113 + 33617167 = 33617280
139 + 33617141 = 33617280
197 + 33617083 = 33617280
211 + 33617069 = 33617280
233 + 33617047 = 33617280

Showing the first eight; more decompositions exist.
