Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16222, here are decompositions:
- 5 + 16217 = 16222
- 29 + 16193 = 16222
- 83 + 16139 = 16222
- 131 + 16091 = 16222
- 149 + 16073 = 16222
- 251 + 15971 = 16222
- 263 + 15959 = 16222
- 419 + 15803 = 16222
Showing the first eight; more decompositions exist.
