Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 118178, here are decompositions:
- 7 + 118171 = 118178
- 31 + 118147 = 118178
- 97 + 118081 = 118178
- 127 + 118051 = 118178
- 199 + 117979 = 118178
- 241 + 117937 = 118178
- 337 + 117841 = 118178
- 367 + 117811 = 118178
Showing the first eight; more decompositions exist.
