Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67824, here are decompositions:
- 5 + 67819 = 67824
- 17 + 67807 = 67824
- 23 + 67801 = 67824
- 41 + 67783 = 67824
- 47 + 67777 = 67824
- 61 + 67763 = 67824
- 67 + 67757 = 67824
- 73 + 67751 = 67824
Showing the first eight; more decompositions exist.
