Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15996, here are decompositions:
- 5 + 15991 = 15996
- 23 + 15973 = 15996
- 37 + 15959 = 15996
- 59 + 15937 = 15996
- 73 + 15923 = 15996
- 83 + 15913 = 15996
- 89 + 15907 = 15996
- 107 + 15889 = 15996
Showing the first eight; more decompositions exist.
