Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546270, here are decompositions:
- 3 + 31546267 = 31546270
- 53 + 31546217 = 31546270
- 71 + 31546199 = 31546270
- 83 + 31546187 = 31546270
- 89 + 31546181 = 31546270
- 251 + 31546019 = 31546270
- 257 + 31546013 = 31546270
- 263 + 31546007 = 31546270
Showing the first eight; more decompositions exist.
