Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19328, here are decompositions:
- 19 + 19309 = 19328
- 61 + 19267 = 19328
- 79 + 19249 = 19328
- 97 + 19231 = 19328
- 109 + 19219 = 19328
- 241 + 19087 = 19328
- 277 + 19051 = 19328
- 349 + 18979 = 19328
Showing the first eight; more decompositions exist.
