Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15716, here are decompositions:
- 37 + 15679 = 15716
- 67 + 15649 = 15716
- 73 + 15643 = 15716
- 97 + 15619 = 15716
- 109 + 15607 = 15716
- 157 + 15559 = 15716
- 223 + 15493 = 15716
- 277 + 15439 = 15716
Showing the first eight; more decompositions exist.
