Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84280, here are decompositions:
- 17 + 84263 = 84280
- 41 + 84239 = 84280
- 59 + 84221 = 84280
- 89 + 84191 = 84280
- 101 + 84179 = 84280
- 137 + 84143 = 84280
- 149 + 84131 = 84280
- 191 + 84089 = 84280
Showing the first eight; more decompositions exist.
