Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31804, here are decompositions:
- 5 + 31799 = 31804
- 11 + 31793 = 31804
- 53 + 31751 = 31804
- 83 + 31721 = 31804
- 137 + 31667 = 31804
- 197 + 31607 = 31804
- 257 + 31547 = 31804
- 263 + 31541 = 31804
Showing the first eight; more decompositions exist.
