Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12584, here are decompositions:
- 7 + 12577 = 12584
- 31 + 12553 = 12584
- 37 + 12547 = 12584
- 43 + 12541 = 12584
- 67 + 12517 = 12584
- 73 + 12511 = 12584
- 97 + 12487 = 12584
- 127 + 12457 = 12584
Showing the first eight; more decompositions exist.
