Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22408, here are decompositions:
- 11 + 22397 = 22408
- 17 + 22391 = 22408
- 41 + 22367 = 22408
- 59 + 22349 = 22408
- 101 + 22307 = 22408
- 131 + 22277 = 22408
- 137 + 22271 = 22408
- 149 + 22259 = 22408
Showing the first eight; more decompositions exist.
