Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16870, here are decompositions:
- 41 + 16829 = 16870
- 47 + 16823 = 16870
- 59 + 16811 = 16870
- 83 + 16787 = 16870
- 107 + 16763 = 16870
- 167 + 16703 = 16870
- 179 + 16691 = 16870
- 197 + 16673 = 16870
Showing the first eight; more decompositions exist.
