Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55842, here are decompositions:
- 5 + 55837 = 55842
- 13 + 55829 = 55842
- 19 + 55823 = 55842
- 23 + 55819 = 55842
- 29 + 55813 = 55842
- 43 + 55799 = 55842
- 79 + 55763 = 55842
- 109 + 55733 = 55842
Showing the first eight; more decompositions exist.
