Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19190, here are decompositions:
- 7 + 19183 = 19190
- 103 + 19087 = 19190
- 109 + 19081 = 19190
- 139 + 19051 = 19190
- 181 + 19009 = 19190
- 211 + 18979 = 19190
- 271 + 18919 = 19190
- 277 + 18913 = 19190
Showing the first eight; more decompositions exist.
