Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31748, here are decompositions:
- 7 + 31741 = 31748
- 19 + 31729 = 31748
- 61 + 31687 = 31748
- 181 + 31567 = 31748
- 271 + 31477 = 31748
- 421 + 31327 = 31748
- 499 + 31249 = 31748
- 571 + 31177 = 31748
Showing the first eight; more decompositions exist.
