Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13178, here are decompositions:
- 7 + 13171 = 13178
- 19 + 13159 = 13178
- 31 + 13147 = 13178
- 79 + 13099 = 13178
- 199 + 12979 = 13178
- 211 + 12967 = 13178
- 271 + 12907 = 13178
- 337 + 12841 = 13178
Showing the first eight; more decompositions exist.
