Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543310, here are decompositions:
- 37 + 31543273 = 31543310
- 67 + 31543243 = 31543310
- 79 + 31543231 = 31543310
- 103 + 31543207 = 31543310
- 241 + 31543069 = 31543310
- 367 + 31542943 = 31543310
- 373 + 31542937 = 31543310
- 433 + 31542877 = 31543310
Showing the first eight; more decompositions exist.
