Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51340, here are decompositions:
- 11 + 51329 = 51340
- 53 + 51287 = 51340
- 83 + 51257 = 51340
- 101 + 51239 = 51340
- 137 + 51203 = 51340
- 269 + 51071 = 51340
- 281 + 51059 = 51340
- 293 + 51047 = 51340
Showing the first eight; more decompositions exist.
