Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66198, here are decompositions:
- 7 + 66191 = 66198
- 19 + 66179 = 66198
- 29 + 66169 = 66198
- 37 + 66161 = 66198
- 61 + 66137 = 66198
- 89 + 66109 = 66198
- 109 + 66089 = 66198
- 127 + 66071 = 66198
Showing the first eight; more decompositions exist.
