Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518326, here are decompositions:
- 13 + 31518313 = 31518326
- 67 + 31518259 = 31518326
- 97 + 31518229 = 31518326
- 163 + 31518163 = 31518326
- 277 + 31518049 = 31518326
- 373 + 31517953 = 31518326
- 439 + 31517887 = 31518326
- 577 + 31517749 = 31518326
Showing the first eight; more decompositions exist.
