Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19320, here are decompositions:
- 11 + 19309 = 19320
- 19 + 19301 = 19320
- 31 + 19289 = 19320
- 47 + 19273 = 19320
- 53 + 19267 = 19320
- 61 + 19259 = 19320
- 71 + 19249 = 19320
- 83 + 19237 = 19320
Showing the first eight; more decompositions exist.
