Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546186, here are decompositions:
- 5 + 31546181 = 31546186
- 167 + 31546019 = 31546186
- 173 + 31546013 = 31546186
- 179 + 31546007 = 31546186
- 227 + 31545959 = 31546186
- 233 + 31545953 = 31546186
- 263 + 31545923 = 31546186
- 443 + 31545743 = 31546186
Showing the first eight; more decompositions exist.
