Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31696, here are decompositions:
- 29 + 31667 = 31696
- 47 + 31649 = 31696
- 53 + 31643 = 31696
- 89 + 31607 = 31696
- 113 + 31583 = 31696
- 149 + 31547 = 31696
- 179 + 31517 = 31696
- 227 + 31469 = 31696
Showing the first eight; more decompositions exist.
