Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123168, here are decompositions:
- 41 + 123127 = 123168
- 47 + 123121 = 123168
- 109 + 123059 = 123168
- 137 + 123031 = 123168
- 151 + 123017 = 123168
- 167 + 123001 = 123168
- 197 + 122971 = 123168
- 211 + 122957 = 123168
Showing the first eight; more decompositions exist.
