Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51384, here are decompositions:
- 23 + 51361 = 51384
- 37 + 51347 = 51384
- 41 + 51343 = 51384
- 43 + 51341 = 51384
- 97 + 51287 = 51384
- 101 + 51283 = 51384
- 127 + 51257 = 51384
- 167 + 51217 = 51384
Showing the first eight; more decompositions exist.
