Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84240, here are decompositions:
- 11 + 84229 = 84240
- 17 + 84223 = 84240
- 19 + 84221 = 84240
- 29 + 84211 = 84240
- 41 + 84199 = 84240
- 59 + 84181 = 84240
- 61 + 84179 = 84240
- 97 + 84143 = 84240
Showing the first eight; more decompositions exist.
