Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26870, here are decompositions:
- 7 + 26863 = 26870
- 31 + 26839 = 26870
- 37 + 26833 = 26870
- 139 + 26731 = 26870
- 157 + 26713 = 26870
- 223 + 26647 = 26870
- 229 + 26641 = 26870
- 313 + 26557 = 26870
Showing the first eight; more decompositions exist.
