Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57942, here are decompositions:
- 19 + 57923 = 57942
- 41 + 57901 = 57942
- 43 + 57899 = 57942
- 61 + 57881 = 57942
- 83 + 57859 = 57942
- 89 + 57853 = 57942
- 103 + 57839 = 57942
- 113 + 57829 = 57942
Showing the first eight; more decompositions exist.
