Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22500, here are decompositions:
- 17 + 22483 = 22500
- 19 + 22481 = 22500
- 31 + 22469 = 22500
- 47 + 22453 = 22500
- 53 + 22447 = 22500
- 59 + 22441 = 22500
- 67 + 22433 = 22500
- 103 + 22397 = 22500
Showing the first eight; more decompositions exist.
