Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28526, here are decompositions:
- 13 + 28513 = 28526
- 79 + 28447 = 28526
- 97 + 28429 = 28526
- 139 + 28387 = 28526
- 229 + 28297 = 28526
- 307 + 28219 = 28526
- 439 + 28087 = 28526
- 457 + 28069 = 28526
Showing the first eight; more decompositions exist.
