Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19358, here are decompositions:
- 109 + 19249 = 19358
- 127 + 19231 = 19358
- 139 + 19219 = 19358
- 151 + 19207 = 19358
- 271 + 19087 = 19358
- 277 + 19081 = 19358
- 307 + 19051 = 19358
- 349 + 19009 = 19358
Showing the first eight; more decompositions exist.
