Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5198, here are decompositions:
- 19 + 5179 = 5198
- 31 + 5167 = 5198
- 79 + 5119 = 5198
- 97 + 5101 = 5198
- 139 + 5059 = 5198
- 199 + 4999 = 5198
- 211 + 4987 = 5198
- 229 + 4969 = 5198
Showing the first eight; more decompositions exist.
