Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15736, here are decompositions:
- 3 + 15733 = 15736
- 5 + 15731 = 15736
- 53 + 15683 = 15736
- 89 + 15647 = 15736
- 107 + 15629 = 15736
- 167 + 15569 = 15736
- 239 + 15497 = 15736
- 263 + 15473 = 15736
Showing the first eight; more decompositions exist.
