Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42222, here are decompositions:
- 13 + 42209 = 42222
- 29 + 42193 = 42222
- 41 + 42181 = 42222
- 43 + 42179 = 42222
- 53 + 42169 = 42222
- 83 + 42139 = 42222
- 139 + 42083 = 42222
- 149 + 42073 = 42222
Showing the first eight; more decompositions exist.
