Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26978, here are decompositions:
- 19 + 26959 = 26978
- 31 + 26947 = 26978
- 97 + 26881 = 26978
- 139 + 26839 = 26978
- 157 + 26821 = 26978
- 241 + 26737 = 26978
- 277 + 26701 = 26978
- 331 + 26647 = 26978
Showing the first eight; more decompositions exist.
