Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454, here are decompositions:
- 61 + 31393 = 31454
- 67 + 31387 = 31454
- 97 + 31357 = 31454
- 127 + 31327 = 31454
- 223 + 31231 = 31454
- 271 + 31183 = 31454
- 277 + 31177 = 31454
- 307 + 31147 = 31454
Showing the first eight; more decompositions exist.
