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.
