Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468212, here are decompositions:
- 11 + 31468201 = 31468212
- 43 + 31468169 = 31468212
- 53 + 31468159 = 31468212
- 199 + 31468013 = 31468212
- 211 + 31468001 = 31468212
- 229 + 31467983 = 31468212
- 263 + 31467949 = 31468212
- 313 + 31467899 = 31468212
Showing the first eight; more decompositions exist.
