Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2882, here are decompositions:
- 3 + 2879 = 2882
- 31 + 2851 = 2882
- 79 + 2803 = 2882
- 151 + 2731 = 2882
- 163 + 2719 = 2882
- 193 + 2689 = 2882
- 199 + 2683 = 2882
- 211 + 2671 = 2882
Showing the first eight; more decompositions exist.
