Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474, here are decompositions:
- 5 + 31469 = 31474
- 83 + 31391 = 31474
- 137 + 31337 = 31474
- 167 + 31307 = 31474
- 197 + 31277 = 31474
- 227 + 31247 = 31474
- 251 + 31223 = 31474
- 281 + 31193 = 31474
Showing the first eight; more decompositions exist.
