Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2222, here are decompositions:
- 19 + 2203 = 2222
- 43 + 2179 = 2222
- 61 + 2161 = 2222
- 79 + 2143 = 2222
- 109 + 2113 = 2222
- 139 + 2083 = 2222
- 193 + 2029 = 2222
- 211 + 2011 = 2222
Showing the first eight; more decompositions exist.
