Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84102, here are decompositions:
- 13 + 84089 = 84102
- 41 + 84061 = 84102
- 43 + 84059 = 84102
- 163 + 83939 = 84102
- 181 + 83921 = 84102
- 191 + 83911 = 84102
- 199 + 83903 = 84102
- 211 + 83891 = 84102
Showing the first eight; more decompositions exist.
