Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4198, here are decompositions:
- 41 + 4157 = 4198
- 59 + 4139 = 4198
- 71 + 4127 = 4198
- 107 + 4091 = 4198
- 149 + 4049 = 4198
- 179 + 4019 = 4198
- 191 + 4007 = 4198
- 197 + 4001 = 4198
Showing the first eight; more decompositions exist.
