Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10280, here are decompositions:

7 + 10273 = 10280
13 + 10267 = 10280
37 + 10243 = 10280
103 + 10177 = 10280
139 + 10141 = 10280
181 + 10099 = 10280
211 + 10069 = 10280
241 + 10039 = 10280

Showing the first eight; more decompositions exist.
