Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122158, here are decompositions:
- 11 + 122147 = 122158
- 41 + 122117 = 122158
- 59 + 122099 = 122158
- 89 + 122069 = 122158
- 107 + 122051 = 122158
- 131 + 122027 = 122158
- 137 + 122021 = 122158
- 191 + 121967 = 122158
Showing the first eight; more decompositions exist.
