Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 24090, here are decompositions:
- 7 + 24083 = 24090
- 13 + 24077 = 24090
- 19 + 24071 = 24090
- 29 + 24061 = 24090
- 41 + 24049 = 24090
- 47 + 24043 = 24090
- 61 + 24029 = 24090
- 67 + 24023 = 24090
Showing the first eight; more decompositions exist.
