Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67240, here are decompositions:
- 23 + 67217 = 67240
- 29 + 67211 = 67240
- 53 + 67187 = 67240
- 59 + 67181 = 67240
- 71 + 67169 = 67240
- 83 + 67157 = 67240
- 101 + 67139 = 67240
- 137 + 67103 = 67240
Showing the first eight; more decompositions exist.
