Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40198, here are decompositions:
- 5 + 40193 = 40198
- 29 + 40169 = 40198
- 47 + 40151 = 40198
- 71 + 40127 = 40198
- 167 + 40031 = 40198
- 227 + 39971 = 40198
- 269 + 39929 = 40198
- 311 + 39887 = 40198
Showing the first eight; more decompositions exist.
