Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527132, here are decompositions:
- 23 + 31527109 = 31527132
- 179 + 31526953 = 31527132
- 191 + 31526941 = 31527132
- 193 + 31526939 = 31527132
- 211 + 31526921 = 31527132
- 229 + 31526903 = 31527132
- 233 + 31526899 = 31527132
- 239 + 31526893 = 31527132
Showing the first eight; more decompositions exist.
