Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2848, here are decompositions:
- 5 + 2843 = 2848
- 11 + 2837 = 2848
- 29 + 2819 = 2848
- 47 + 2801 = 2848
- 59 + 2789 = 2848
- 71 + 2777 = 2848
- 107 + 2741 = 2848
- 137 + 2711 = 2848
Showing the first eight; more decompositions exist.
