Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19226, here are decompositions:
- 7 + 19219 = 19226
- 13 + 19213 = 19226
- 19 + 19207 = 19226
- 43 + 19183 = 19226
- 139 + 19087 = 19226
- 157 + 19069 = 19226
- 307 + 18919 = 19226
- 313 + 18913 = 19226
Showing the first eight; more decompositions exist.
