Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22170, here are decompositions:
- 11 + 22159 = 22170
- 13 + 22157 = 22170
- 17 + 22153 = 22170
- 23 + 22147 = 22170
- 37 + 22133 = 22170
- 41 + 22129 = 22170
- 47 + 22123 = 22170
- 59 + 22111 = 22170
Showing the first eight; more decompositions exist.
