Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23880, here are decompositions:
- 7 + 23873 = 23880
- 11 + 23869 = 23880
- 23 + 23857 = 23880
- 47 + 23833 = 23880
- 53 + 23827 = 23880
- 61 + 23819 = 23880
- 67 + 23813 = 23880
- 79 + 23801 = 23880
Showing the first eight; more decompositions exist.
