Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2958, here are decompositions:
- 5 + 2953 = 2958
- 19 + 2939 = 2958
- 31 + 2927 = 2958
- 41 + 2917 = 2958
- 61 + 2897 = 2958
- 71 + 2887 = 2958
- 79 + 2879 = 2958
- 97 + 2861 = 2958
Showing the first eight; more decompositions exist.
