Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12152, here are decompositions:
- 3 + 12149 = 12152
- 43 + 12109 = 12152
- 79 + 12073 = 12152
- 103 + 12049 = 12152
- 109 + 12043 = 12152
- 181 + 11971 = 12152
- 193 + 11959 = 12152
- 199 + 11953 = 12152
Showing the first eight; more decompositions exist.
