Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22912, here are decompositions:
- 5 + 22907 = 22912
- 11 + 22901 = 22912
- 41 + 22871 = 22912
- 53 + 22859 = 22912
- 59 + 22853 = 22912
- 101 + 22811 = 22912
- 173 + 22739 = 22912
- 191 + 22721 = 22912
Showing the first eight; more decompositions exist.
