Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23978, here are decompositions:
- 7 + 23971 = 23978
- 61 + 23917 = 23978
- 67 + 23911 = 23978
- 79 + 23899 = 23978
- 109 + 23869 = 23978
- 151 + 23827 = 23978
- 211 + 23767 = 23978
- 307 + 23671 = 23978
Showing the first eight; more decompositions exist.
