Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23920, here are decompositions:
- 3 + 23917 = 23920
- 11 + 23909 = 23920
- 41 + 23879 = 23920
- 47 + 23873 = 23920
- 89 + 23831 = 23920
- 101 + 23819 = 23920
- 107 + 23813 = 23920
- 131 + 23789 = 23920
Showing the first eight; more decompositions exist.
