Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19098, here are decompositions:
- 11 + 19087 = 19098
- 17 + 19081 = 19098
- 19 + 19079 = 19098
- 29 + 19069 = 19098
- 47 + 19051 = 19098
- 61 + 19037 = 19098
- 67 + 19031 = 19098
- 89 + 19009 = 19098
Showing the first eight; more decompositions exist.
