Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42982, here are decompositions:
- 3 + 42979 = 42982
- 29 + 42953 = 42982
- 53 + 42929 = 42982
- 59 + 42923 = 42982
- 83 + 42899 = 42982
- 239 + 42743 = 42982
- 263 + 42719 = 42982
- 281 + 42701 = 42982
Showing the first eight; more decompositions exist.
