Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471330, here are decompositions:
- 41 + 31471289 = 31471330
- 113 + 31471217 = 31471330
- 239 + 31471091 = 31471330
- 251 + 31471079 = 31471330
- 353 + 31470977 = 31471330
- 389 + 31470941 = 31471330
- 419 + 31470911 = 31471330
- 461 + 31470869 = 31471330
Showing the first eight; more decompositions exist.
