Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2152, here are decompositions:
- 11 + 2141 = 2152
- 23 + 2129 = 2152
- 41 + 2111 = 2152
- 53 + 2099 = 2152
- 71 + 2081 = 2152
- 83 + 2069 = 2152
- 89 + 2063 = 2152
- 113 + 2039 = 2152
Showing the first eight; more decompositions exist.
