Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166152, here are decompositions:
- 5 + 166147 = 166152
- 53 + 166099 = 166152
- 71 + 166081 = 166152
- 89 + 166063 = 166152
- 109 + 166043 = 166152
- 131 + 166021 = 166152
- 139 + 166013 = 166152
- 191 + 165961 = 166152
Showing the first eight; more decompositions exist.
