Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543304, here are decompositions:
- 3 + 31543301 = 31543304
- 31 + 31543273 = 31543304
- 61 + 31543243 = 31543304
- 73 + 31543231 = 31543304
- 97 + 31543207 = 31543304
- 313 + 31542991 = 31543304
- 337 + 31542967 = 31543304
- 367 + 31542937 = 31543304
Showing the first eight; more decompositions exist.
