Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19082, here are decompositions:
- 3 + 19079 = 19082
- 13 + 19069 = 19082
- 31 + 19051 = 19082
- 73 + 19009 = 19082
- 103 + 18979 = 19082
- 109 + 18973 = 19082
- 163 + 18919 = 19082
- 223 + 18859 = 19082
Showing the first eight; more decompositions exist.
