Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55168, here are decompositions:
- 5 + 55163 = 55168
- 41 + 55127 = 55168
- 59 + 55109 = 55168
- 89 + 55079 = 55168
- 107 + 55061 = 55168
- 167 + 55001 = 55168
- 227 + 54941 = 55168
- 251 + 54917 = 55168
Showing the first eight; more decompositions exist.
