Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22488, here are decompositions:
- 5 + 22483 = 22488
- 7 + 22481 = 22488
- 19 + 22469 = 22488
- 41 + 22447 = 22488
- 47 + 22441 = 22488
- 79 + 22409 = 22488
- 97 + 22391 = 22488
- 107 + 22381 = 22488
Showing the first eight; more decompositions exist.
