Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163824, here are decompositions:
- 5 + 163819 = 163824
- 13 + 163811 = 163824
- 43 + 163781 = 163824
- 53 + 163771 = 163824
- 71 + 163753 = 163824
- 83 + 163741 = 163824
- 127 + 163697 = 163824
- 151 + 163673 = 163824
Showing the first eight; more decompositions exist.
