Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23154, here are decompositions:
- 11 + 23143 = 23154
- 23 + 23131 = 23154
- 37 + 23117 = 23154
- 67 + 23087 = 23154
- 73 + 23081 = 23154
- 83 + 23071 = 23154
- 97 + 23057 = 23154
- 101 + 23053 = 23154
Showing the first eight; more decompositions exist.
