Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25942, here are decompositions:
- 3 + 25939 = 25942
- 11 + 25931 = 25942
- 23 + 25919 = 25942
- 29 + 25913 = 25942
- 53 + 25889 = 25942
- 101 + 25841 = 25942
- 149 + 25793 = 25942
- 179 + 25763 = 25942
Showing the first eight; more decompositions exist.
