Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15952, here are decompositions:
- 29 + 15923 = 15952
- 71 + 15881 = 15952
- 149 + 15803 = 15952
- 179 + 15773 = 15952
- 191 + 15761 = 15952
- 269 + 15683 = 15952
- 281 + 15671 = 15952
- 311 + 15641 = 15952
Showing the first eight; more decompositions exist.
