Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543464, here are decompositions:
- 11 + 31543453 = 31543464
- 13 + 31543451 = 31543464
- 67 + 31543397 = 31543464
- 103 + 31543361 = 31543464
- 163 + 31543301 = 31543464
- 191 + 31543273 = 31543464
- 233 + 31543231 = 31543464
- 241 + 31543223 = 31543464
Showing the first eight; more decompositions exist.
