Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 24142, here are decompositions:
- 5 + 24137 = 24142
- 29 + 24113 = 24142
- 59 + 24083 = 24142
- 71 + 24071 = 24142
- 113 + 24029 = 24142
- 149 + 23993 = 24142
- 233 + 23909 = 24142
- 263 + 23879 = 24142
Showing the first eight; more decompositions exist.
