Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13078, here are decompositions:
- 29 + 13049 = 13078
- 41 + 13037 = 13078
- 71 + 13007 = 13078
- 137 + 12941 = 13078
- 167 + 12911 = 13078
- 179 + 12899 = 13078
- 257 + 12821 = 13078
- 269 + 12809 = 13078
Showing the first eight; more decompositions exist.
