Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15976, here are decompositions:
- 3 + 15973 = 15976
- 5 + 15971 = 15976
- 17 + 15959 = 15976
- 53 + 15923 = 15976
- 89 + 15887 = 15976
- 167 + 15809 = 15976
- 173 + 15803 = 15976
- 179 + 15797 = 15976
Showing the first eight; more decompositions exist.
