Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2846, here are decompositions:
- 3 + 2843 = 2846
- 13 + 2833 = 2846
- 43 + 2803 = 2846
- 79 + 2767 = 2846
- 97 + 2749 = 2846
- 127 + 2719 = 2846
- 139 + 2707 = 2846
- 157 + 2689 = 2846
Showing the first eight; more decompositions exist.
