Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22528, here are decompositions:
- 17 + 22511 = 22528
- 47 + 22481 = 22528
- 59 + 22469 = 22528
- 131 + 22397 = 22528
- 137 + 22391 = 22528
- 179 + 22349 = 22528
- 251 + 22277 = 22528
- 257 + 22271 = 22528
Showing the first eight; more decompositions exist.
