Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31208, here are decompositions:
- 19 + 31189 = 31208
- 31 + 31177 = 31208
- 61 + 31147 = 31208
- 127 + 31081 = 31208
- 139 + 31069 = 31208
- 157 + 31051 = 31208
- 271 + 30937 = 31208
- 277 + 30931 = 31208
Showing the first eight; more decompositions exist.
