Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470448, here are decompositions:
- 5 + 31470443 = 31470448
- 89 + 31470359 = 31470448
- 227 + 31470221 = 31470448
- 239 + 31470209 = 31470448
- 281 + 31470167 = 31470448
- 461 + 31469987 = 31470448
- 587 + 31469861 = 31470448
- 599 + 31469849 = 31470448
Showing the first eight; more decompositions exist.
