Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55840, here are decompositions:
- 3 + 55837 = 55840
- 11 + 55829 = 55840
- 17 + 55823 = 55840
- 23 + 55817 = 55840
- 41 + 55799 = 55840
- 47 + 55793 = 55840
- 53 + 55787 = 55840
- 107 + 55733 = 55840
Showing the first eight; more decompositions exist.
