Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19180, here are decompositions:
- 17 + 19163 = 19180
- 23 + 19157 = 19180
- 41 + 19139 = 19180
- 59 + 19121 = 19180
- 101 + 19079 = 19180
- 107 + 19073 = 19180
- 149 + 19031 = 19180
- 167 + 19013 = 19180
Showing the first eight; more decompositions exist.
