Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543694, here are decompositions:
- 3 + 31543691 = 31543694
- 151 + 31543543 = 31543694
- 163 + 31543531 = 31543694
- 241 + 31543453 = 31543694
- 421 + 31543273 = 31543694
- 463 + 31543231 = 31543694
- 487 + 31543207 = 31543694
- 727 + 31542967 = 31543694
Showing the first eight; more decompositions exist.
