Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66108, here are decompositions:
- 5 + 66103 = 66108
- 19 + 66089 = 66108
- 37 + 66071 = 66108
- 41 + 66067 = 66108
- 61 + 66047 = 66108
- 67 + 66041 = 66108
- 71 + 66037 = 66108
- 79 + 66029 = 66108
Showing the first eight; more decompositions exist.
