Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22920, here are decompositions:
- 13 + 22907 = 22920
- 19 + 22901 = 22920
- 43 + 22877 = 22920
- 59 + 22861 = 22920
- 61 + 22859 = 22920
- 67 + 22853 = 22920
- 103 + 22817 = 22920
- 109 + 22811 = 22920
Showing the first eight; more decompositions exist.
