Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42960, here are decompositions:
- 7 + 42953 = 42960
- 17 + 42943 = 42960
- 23 + 42937 = 42960
- 31 + 42929 = 42960
- 37 + 42923 = 42960
- 59 + 42901 = 42960
- 61 + 42899 = 42960
- 97 + 42863 = 42960
Showing the first eight; more decompositions exist.
