Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15834, here are decompositions:
- 11 + 15823 = 15834
- 17 + 15817 = 15834
- 31 + 15803 = 15834
- 37 + 15797 = 15834
- 43 + 15791 = 15834
- 47 + 15787 = 15834
- 61 + 15773 = 15834
- 67 + 15767 = 15834
Showing the first eight; more decompositions exist.
