Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453742, here are decompositions:
- 31 + 31453711 = 31453742
- 43 + 31453699 = 31453742
- 241 + 31453501 = 31453742
- 349 + 31453393 = 31453742
- 409 + 31453333 = 31453742
- 421 + 31453321 = 31453742
- 571 + 31453171 = 31453742
- 601 + 31453141 = 31453742
Showing the first eight; more decompositions exist.
