Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115198, here are decompositions:
- 47 + 115151 = 115198
- 71 + 115127 = 115198
- 131 + 115067 = 115198
- 137 + 115061 = 115198
- 179 + 115019 = 115198
- 197 + 115001 = 115198
- 257 + 114941 = 115198
- 389 + 114809 = 115198
Showing the first eight; more decompositions exist.
