Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188118, here are decompositions:
- 11 + 188107 = 188118
- 89 + 188029 = 188118
- 97 + 188021 = 188118
- 101 + 188017 = 188118
- 107 + 188011 = 188118
- 131 + 187987 = 188118
- 167 + 187951 = 188118
- 191 + 187927 = 188118
Showing the first eight; more decompositions exist.
