Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16824, here are decompositions:
- 13 + 16811 = 16824
- 37 + 16787 = 16824
- 61 + 16763 = 16824
- 83 + 16741 = 16824
- 131 + 16693 = 16824
- 151 + 16673 = 16824
- 163 + 16661 = 16824
- 167 + 16657 = 16824
Showing the first eight; more decompositions exist.
