Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10102, here are decompositions:
- 3 + 10099 = 10102
- 11 + 10091 = 10102
- 23 + 10079 = 10102
- 41 + 10061 = 10102
- 173 + 9929 = 10102
- 179 + 9923 = 10102
- 251 + 9851 = 10102
- 263 + 9839 = 10102
Showing the first eight; more decompositions exist.
