Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22458, here are decompositions:
- 5 + 22453 = 22458
- 11 + 22447 = 22458
- 17 + 22441 = 22458
- 61 + 22397 = 22458
- 67 + 22391 = 22458
- 89 + 22369 = 22458
- 109 + 22349 = 22458
- 151 + 22307 = 22458
Showing the first eight; more decompositions exist.
