Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19364, here are decompositions:
- 31 + 19333 = 19364
- 97 + 19267 = 19364
- 127 + 19237 = 19364
- 151 + 19213 = 19364
- 157 + 19207 = 19364
- 181 + 19183 = 19364
- 223 + 19141 = 19364
- 277 + 19087 = 19364
Showing the first eight; more decompositions exist.
