Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42008, here are decompositions:
- 61 + 41947 = 42008
- 67 + 41941 = 42008
- 97 + 41911 = 42008
- 157 + 41851 = 42008
- 199 + 41809 = 42008
- 271 + 41737 = 42008
- 349 + 41659 = 42008
- 367 + 41641 = 42008
Showing the first eight; more decompositions exist.
