Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55860, here are decompositions:
- 11 + 55849 = 55860
- 17 + 55843 = 55860
- 23 + 55837 = 55860
- 31 + 55829 = 55860
- 37 + 55823 = 55860
- 41 + 55819 = 55860
- 43 + 55817 = 55860
- 47 + 55813 = 55860
Showing the first eight; more decompositions exist.
