Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19102, here are decompositions:
- 23 + 19079 = 19102
- 29 + 19073 = 19102
- 71 + 19031 = 19102
- 89 + 19013 = 19102
- 101 + 19001 = 19102
- 191 + 18911 = 19102
- 233 + 18869 = 19102
- 263 + 18839 = 19102
Showing the first eight; more decompositions exist.
