Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 582, here are decompositions:
- 5 + 577 = 582
- 11 + 571 = 582
- 13 + 569 = 582
- 19 + 563 = 582
- 41 + 541 = 582
- 59 + 523 = 582
- 61 + 521 = 582
- 73 + 509 = 582
Showing the first eight; more decompositions exist.
