Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22540, here are decompositions:
- 29 + 22511 = 22540
- 59 + 22481 = 22540
- 71 + 22469 = 22540
- 107 + 22433 = 22540
- 131 + 22409 = 22540
- 149 + 22391 = 22540
- 173 + 22367 = 22540
- 191 + 22349 = 22540
Showing the first eight; more decompositions exist.
