Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15712, here are decompositions:
- 29 + 15683 = 15712
- 41 + 15671 = 15712
- 71 + 15641 = 15712
- 83 + 15629 = 15712
- 131 + 15581 = 15712
- 239 + 15473 = 15712
- 251 + 15461 = 15712
- 269 + 15443 = 15712
Showing the first eight; more decompositions exist.
