Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15892, here are decompositions:
- 3 + 15889 = 15892
- 5 + 15887 = 15892
- 11 + 15881 = 15892
- 83 + 15809 = 15892
- 89 + 15803 = 15892
- 101 + 15791 = 15892
- 131 + 15761 = 15892
- 251 + 15641 = 15892
Showing the first eight; more decompositions exist.
