Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55198, here are decompositions:
- 71 + 55127 = 55198
- 89 + 55109 = 55198
- 137 + 55061 = 55198
- 149 + 55049 = 55198
- 197 + 55001 = 55198
- 239 + 54959 = 55198
- 257 + 54941 = 55198
- 281 + 54917 = 55198
Showing the first eight; more decompositions exist.
