Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543904, here are decompositions:
- 31 + 31543873 = 31543904
- 61 + 31543843 = 31543904
- 127 + 31543777 = 31543904
- 181 + 31543723 = 31543904
- 193 + 31543711 = 31543904
- 373 + 31543531 = 31543904
- 631 + 31543273 = 31543904
- 661 + 31543243 = 31543904
Showing the first eight; more decompositions exist.
