Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22212, here are decompositions:
- 19 + 22193 = 22212
- 23 + 22189 = 22212
- 41 + 22171 = 22212
- 53 + 22159 = 22212
- 59 + 22153 = 22212
- 79 + 22133 = 22212
- 83 + 22129 = 22212
- 89 + 22123 = 22212
Showing the first eight; more decompositions exist.
