Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17528, here are decompositions:
- 19 + 17509 = 17528
- 31 + 17497 = 17528
- 37 + 17491 = 17528
- 61 + 17467 = 17528
- 79 + 17449 = 17528
- 97 + 17431 = 17528
- 109 + 17419 = 17528
- 127 + 17401 = 17528
Showing the first eight; more decompositions exist.
