Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15726, here are decompositions:
- 43 + 15683 = 15726
- 47 + 15679 = 15726
- 59 + 15667 = 15726
- 79 + 15647 = 15726
- 83 + 15643 = 15726
- 97 + 15629 = 15726
- 107 + 15619 = 15726
- 157 + 15569 = 15726
Showing the first eight; more decompositions exist.
