Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19142, here are decompositions:
- 3 + 19139 = 19142
- 61 + 19081 = 19142
- 73 + 19069 = 19142
- 163 + 18979 = 19142
- 223 + 18919 = 19142
- 229 + 18913 = 19142
- 283 + 18859 = 19142
- 349 + 18793 = 19142
Showing the first eight; more decompositions exist.
