Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546210, here are decompositions:
- 11 + 31546199 = 31546210
- 23 + 31546187 = 31546210
- 29 + 31546181 = 31546210
- 191 + 31546019 = 31546210
- 197 + 31546013 = 31546210
- 251 + 31545959 = 31546210
- 257 + 31545953 = 31546210
- 461 + 31545749 = 31546210
Showing the first eight; more decompositions exist.
