Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531526, here are decompositions:
- 3 + 31531523 = 31531526
- 43 + 31531483 = 31531526
- 73 + 31531453 = 31531526
- 109 + 31531417 = 31531526
- 127 + 31531399 = 31531526
- 157 + 31531369 = 31531526
- 223 + 31531303 = 31531526
- 277 + 31531249 = 31531526
Showing the first eight; more decompositions exist.
