Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42022, here are decompositions:
- 3 + 42019 = 42022
- 5 + 42017 = 42022
- 23 + 41999 = 42022
- 41 + 41981 = 42022
- 53 + 41969 = 42022
- 173 + 41849 = 42022
- 179 + 41843 = 42022
- 251 + 41771 = 42022
Showing the first eight; more decompositions exist.
