Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28512, here are decompositions:
- 13 + 28499 = 28512
- 19 + 28493 = 28512
- 73 + 28439 = 28512
- 79 + 28433 = 28512
- 83 + 28429 = 28512
- 101 + 28411 = 28512
- 103 + 28409 = 28512
- 109 + 28403 = 28512
Showing the first eight; more decompositions exist.
