Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518226, here are decompositions:
- 17 + 31518209 = 31518226
- 29 + 31518197 = 31518226
- 53 + 31518173 = 31518226
- 137 + 31518089 = 31518226
- 227 + 31517999 = 31518226
- 263 + 31517963 = 31518226
- 317 + 31517909 = 31518226
- 347 + 31517879 = 31518226
Showing the first eight; more decompositions exist.
