Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23990, here are decompositions:
- 13 + 23977 = 23990
- 19 + 23971 = 23990
- 61 + 23929 = 23990
- 73 + 23917 = 23990
- 79 + 23911 = 23990
- 97 + 23893 = 23990
- 103 + 23887 = 23990
- 157 + 23833 = 23990
Showing the first eight; more decompositions exist.
