Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6240, here are decompositions:
- 11 + 6229 = 6240
- 19 + 6221 = 6240
- 23 + 6217 = 6240
- 29 + 6211 = 6240
- 37 + 6203 = 6240
- 41 + 6199 = 6240
- 43 + 6197 = 6240
- 67 + 6173 = 6240
Showing the first eight; more decompositions exist.
