Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543410, here are decompositions:
- 13 + 31543397 = 31543410
- 61 + 31543349 = 31543410
- 79 + 31543331 = 31543410
- 109 + 31543301 = 31543410
- 137 + 31543273 = 31543410
- 167 + 31543243 = 31543410
- 179 + 31543231 = 31543410
- 191 + 31543219 = 31543410
Showing the first eight; more decompositions exist.
