Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 118118, here are decompositions:
- 37 + 118081 = 118118
- 61 + 118057 = 118118
- 67 + 118051 = 118118
- 127 + 117991 = 118118
- 139 + 117979 = 118118
- 181 + 117937 = 118118
- 229 + 117889 = 118118
- 241 + 117877 = 118118
Showing the first eight; more decompositions exist.
