Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531704, here are decompositions:
- 37 + 31531667 = 31531704
- 181 + 31531523 = 31531704
- 233 + 31531471 = 31531704
- 251 + 31531453 = 31531704
- 283 + 31531421 = 31531704
- 401 + 31531303 = 31531704
- 431 + 31531273 = 31531704
- 433 + 31531271 = 31531704
Showing the first eight; more decompositions exist.
