Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68842, here are decompositions:
- 23 + 68819 = 68842
- 29 + 68813 = 68842
- 71 + 68771 = 68842
- 113 + 68729 = 68842
- 131 + 68711 = 68842
- 173 + 68669 = 68842
- 311 + 68531 = 68842
- 353 + 68489 = 68842
Showing the first eight; more decompositions exist.
