Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22188, here are decompositions:
- 17 + 22171 = 22188
- 29 + 22159 = 22188
- 31 + 22157 = 22188
- 41 + 22147 = 22188
- 59 + 22129 = 22188
- 79 + 22109 = 22188
- 97 + 22091 = 22188
- 109 + 22079 = 22188
Showing the first eight; more decompositions exist.
