Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 876, here are decompositions:
- 13 + 863 = 876
- 17 + 859 = 876
- 19 + 857 = 876
- 23 + 853 = 876
- 37 + 839 = 876
- 47 + 829 = 876
- 53 + 823 = 876
- 67 + 809 = 876
Showing the first eight; more decompositions exist.
