Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20582, here are decompositions:
- 19 + 20563 = 20582
- 31 + 20551 = 20582
- 61 + 20521 = 20582
- 73 + 20509 = 20582
- 103 + 20479 = 20582
- 139 + 20443 = 20582
- 151 + 20431 = 20582
- 193 + 20389 = 20582
Showing the first eight; more decompositions exist.
