Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12222, here are decompositions:
- 11 + 12211 = 12222
- 19 + 12203 = 12222
- 59 + 12163 = 12222
- 61 + 12161 = 12222
- 73 + 12149 = 12222
- 79 + 12143 = 12222
- 103 + 12119 = 12222
- 109 + 12113 = 12222
Showing the first eight; more decompositions exist.
