Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2876, here are decompositions:
- 19 + 2857 = 2876
- 43 + 2833 = 2876
- 73 + 2803 = 2876
- 79 + 2797 = 2876
- 109 + 2767 = 2876
- 127 + 2749 = 2876
- 157 + 2719 = 2876
- 163 + 2713 = 2876
Showing the first eight; more decompositions exist.
