Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23156, here are decompositions:
- 13 + 23143 = 23156
- 97 + 23059 = 23156
- 103 + 23053 = 23156
- 127 + 23029 = 23156
- 139 + 23017 = 23156
- 163 + 22993 = 23156
- 193 + 22963 = 23156
- 349 + 22807 = 23156
Showing the first eight; more decompositions exist.
