Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 118216, here are decompositions:
- 3 + 118213 = 118216
- 5 + 118211 = 118216
- 47 + 118169 = 118216
- 53 + 118163 = 118216
- 89 + 118127 = 118216
- 173 + 118043 = 118216
- 179 + 118037 = 118216
- 227 + 117989 = 118216
Showing the first eight; more decompositions exist.
