Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17538, here are decompositions:
- 19 + 17519 = 17538
- 29 + 17509 = 17538
- 41 + 17497 = 17538
- 47 + 17491 = 17538
- 61 + 17477 = 17538
- 67 + 17471 = 17538
- 71 + 17467 = 17538
- 89 + 17449 = 17538
Showing the first eight; more decompositions exist.
