Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19168, here are decompositions:
- 5 + 19163 = 19168
- 11 + 19157 = 19168
- 29 + 19139 = 19168
- 47 + 19121 = 19168
- 89 + 19079 = 19168
- 131 + 19037 = 19168
- 137 + 19031 = 19168
- 167 + 19001 = 19168
Showing the first eight; more decompositions exist.
