Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26940, here are decompositions:
- 13 + 26927 = 26940
- 19 + 26921 = 26940
- 37 + 26903 = 26940
- 47 + 26893 = 26940
- 59 + 26881 = 26940
- 61 + 26879 = 26940
- 79 + 26861 = 26940
- 101 + 26839 = 26940
Showing the first eight; more decompositions exist.
