Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55816, here are decompositions:
- 3 + 55813 = 55816
- 17 + 55799 = 55816
- 23 + 55793 = 55816
- 29 + 55787 = 55816
- 53 + 55763 = 55816
- 83 + 55733 = 55816
- 149 + 55667 = 55816
- 197 + 55619 = 55816
Showing the first eight; more decompositions exist.
