Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25522, here are decompositions:
- 53 + 25469 = 25522
- 59 + 25463 = 25522
- 83 + 25439 = 25522
- 113 + 25409 = 25522
- 131 + 25391 = 25522
- 149 + 25373 = 25522
- 173 + 25349 = 25522
- 179 + 25343 = 25522
Showing the first eight; more decompositions exist.
