Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12582, here are decompositions:
- 5 + 12577 = 12582
- 13 + 12569 = 12582
- 29 + 12553 = 12582
- 41 + 12541 = 12582
- 43 + 12539 = 12582
- 71 + 12511 = 12582
- 79 + 12503 = 12582
- 103 + 12479 = 12582
Showing the first eight; more decompositions exist.
