Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125198, here are decompositions:
- 67 + 125131 = 125198
- 79 + 125119 = 125198
- 97 + 125101 = 125198
- 181 + 125017 = 125198
- 211 + 124987 = 125198
- 379 + 124819 = 125198
- 421 + 124777 = 125198
- 439 + 124759 = 125198
Showing the first eight; more decompositions exist.
