Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28576, here are decompositions:
- 3 + 28573 = 28576
- 5 + 28571 = 28576
- 17 + 28559 = 28576
- 29 + 28547 = 28576
- 59 + 28517 = 28576
- 83 + 28493 = 28576
- 113 + 28463 = 28576
- 137 + 28439 = 28576
Showing the first eight; more decompositions exist.
