Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90280, here are decompositions:

17 + 90263 = 90280
41 + 90239 = 90280
53 + 90227 = 90280
83 + 90197 = 90280
89 + 90191 = 90280
107 + 90173 = 90280
131 + 90149 = 90280
173 + 90107 = 90280

Showing the first eight; more decompositions exist.
