Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526, here are decompositions:
- 13 + 31513 = 31526
- 37 + 31489 = 31526
- 139 + 31387 = 31526
- 193 + 31333 = 31526
- 199 + 31327 = 31526
- 277 + 31249 = 31526
- 307 + 31219 = 31526
- 337 + 31189 = 31526
Showing the first eight; more decompositions exist.
