Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2894, here are decompositions:
- 7 + 2887 = 2894
- 37 + 2857 = 2894
- 43 + 2851 = 2894
- 61 + 2833 = 2894
- 97 + 2797 = 2894
- 103 + 2791 = 2894
- 127 + 2767 = 2894
- 163 + 2731 = 2894
Showing the first eight; more decompositions exist.
