Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84400, here are decompositions:
- 11 + 84389 = 84400
- 23 + 84377 = 84400
- 53 + 84347 = 84400
- 83 + 84317 = 84400
- 101 + 84299 = 84400
- 137 + 84263 = 84400
- 179 + 84221 = 84400
- 257 + 84143 = 84400
Showing the first eight; more decompositions exist.
