Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504, here are decompositions:
- 23 + 31481 = 31504
- 107 + 31397 = 31504
- 113 + 31391 = 31504
- 167 + 31337 = 31504
- 197 + 31307 = 31504
- 227 + 31277 = 31504
- 233 + 31271 = 31504
- 251 + 31253 = 31504
Showing the first eight; more decompositions exist.
