Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2182, here are decompositions:
- 3 + 2179 = 2182
- 29 + 2153 = 2182
- 41 + 2141 = 2182
- 53 + 2129 = 2182
- 71 + 2111 = 2182
- 83 + 2099 = 2182
- 101 + 2081 = 2182
- 113 + 2069 = 2182
Showing the first eight; more decompositions exist.
