Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28518, here are decompositions:
- 5 + 28513 = 28518
- 19 + 28499 = 28518
- 41 + 28477 = 28518
- 71 + 28447 = 28518
- 79 + 28439 = 28518
- 89 + 28429 = 28518
- 107 + 28411 = 28518
- 109 + 28409 = 28518
Showing the first eight; more decompositions exist.
