Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2824, here are decompositions:
- 5 + 2819 = 2824
- 23 + 2801 = 2824
- 47 + 2777 = 2824
- 71 + 2753 = 2824
- 83 + 2741 = 2824
- 113 + 2711 = 2824
- 131 + 2693 = 2824
- 137 + 2687 = 2824
Showing the first eight; more decompositions exist.
