Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81834, here are decompositions:
- 17 + 81817 = 81834
- 61 + 81773 = 81834
- 73 + 81761 = 81834
- 97 + 81737 = 81834
- 107 + 81727 = 81834
- 127 + 81707 = 81834
- 131 + 81703 = 81834
- 157 + 81677 = 81834
Showing the first eight; more decompositions exist.
