Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188168, here are decompositions:
- 31 + 188137 = 188168
- 61 + 188107 = 188168
- 139 + 188029 = 188168
- 151 + 188017 = 188168
- 157 + 188011 = 188168
- 181 + 187987 = 188168
- 241 + 187927 = 188168
- 271 + 187897 = 188168
Showing the first eight; more decompositions exist.
