Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546240, here are decompositions:
- 23 + 31546217 = 31546240
- 41 + 31546199 = 31546240
- 53 + 31546187 = 31546240
- 59 + 31546181 = 31546240
- 227 + 31546013 = 31546240
- 233 + 31546007 = 31546240
- 281 + 31545959 = 31546240
- 317 + 31545923 = 31546240
Showing the first eight; more decompositions exist.
