Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31738, here are decompositions:
- 11 + 31727 = 31738
- 17 + 31721 = 31738
- 71 + 31667 = 31738
- 89 + 31649 = 31738
- 131 + 31607 = 31738
- 137 + 31601 = 31738
- 191 + 31547 = 31738
- 197 + 31541 = 31738
Showing the first eight; more decompositions exist.
