Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11942, here are decompositions:
- 3 + 11939 = 11942
- 19 + 11923 = 11942
- 79 + 11863 = 11942
- 103 + 11839 = 11942
- 109 + 11833 = 11942
- 163 + 11779 = 11942
- 199 + 11743 = 11942
- 211 + 11731 = 11942
Showing the first eight; more decompositions exist.
