Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66888, here are decompositions:
- 5 + 66883 = 66888
- 11 + 66877 = 66888
- 37 + 66851 = 66888
- 47 + 66841 = 66888
- 67 + 66821 = 66888
- 79 + 66809 = 66888
- 97 + 66791 = 66888
- 137 + 66751 = 66888
Showing the first eight; more decompositions exist.
