Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23972, here are decompositions:
- 43 + 23929 = 23972
- 61 + 23911 = 23972
- 73 + 23899 = 23972
- 79 + 23893 = 23972
- 103 + 23869 = 23972
- 139 + 23833 = 23972
- 199 + 23773 = 23972
- 211 + 23761 = 23972
Showing the first eight; more decompositions exist.
