Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22166, here are decompositions:
- 7 + 22159 = 22166
- 13 + 22153 = 22166
- 19 + 22147 = 22166
- 37 + 22129 = 22166
- 43 + 22123 = 22166
- 73 + 22093 = 22166
- 103 + 22063 = 22166
- 127 + 22039 = 22166
Showing the first eight; more decompositions exist.
