Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661198, here are decompositions:
- 5 + 8661193 = 8661198
- 17 + 8661181 = 8661198
- 37 + 8661161 = 8661198
- 61 + 8661137 = 8661198
- 79 + 8661119 = 8661198
- 109 + 8661089 = 8661198
- 137 + 8661061 = 8661198
- 149 + 8661049 = 8661198
Showing the first eight; more decompositions exist.
