Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470758, here are decompositions:
- 37 + 31470721 = 31470758
- 97 + 31470661 = 31470758
- 139 + 31470619 = 31470758
- 211 + 31470547 = 31470758
- 349 + 31470409 = 31470758
- 379 + 31470379 = 31470758
- 421 + 31470337 = 31470758
- 499 + 31470259 = 31470758
Showing the first eight; more decompositions exist.
