Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82142, here are decompositions:
- 3 + 82139 = 82142
- 13 + 82129 = 82142
- 103 + 82039 = 82142
- 139 + 82003 = 82142
- 199 + 81943 = 82142
- 211 + 81931 = 82142
- 223 + 81919 = 82142
- 241 + 81901 = 82142
Showing the first eight; more decompositions exist.
