Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15832, here are decompositions:
- 23 + 15809 = 15832
- 29 + 15803 = 15832
- 41 + 15791 = 15832
- 59 + 15773 = 15832
- 71 + 15761 = 15832
- 83 + 15749 = 15832
- 101 + 15731 = 15832
- 149 + 15683 = 15832
Showing the first eight; more decompositions exist.
