Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42066, here are decompositions:
- 5 + 42061 = 42066
- 23 + 42043 = 42066
- 43 + 42023 = 42066
- 47 + 42019 = 42066
- 53 + 42013 = 42066
- 67 + 41999 = 42066
- 83 + 41983 = 42066
- 97 + 41969 = 42066
Showing the first eight; more decompositions exist.
