Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31958, here are decompositions:
- 67 + 31891 = 31958
- 109 + 31849 = 31958
- 229 + 31729 = 31958
- 271 + 31687 = 31958
- 331 + 31627 = 31958
- 571 + 31387 = 31958
- 601 + 31357 = 31958
- 631 + 31327 = 31958
Showing the first eight; more decompositions exist.
