Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12558, here are decompositions:
- 5 + 12553 = 12558
- 11 + 12547 = 12558
- 17 + 12541 = 12558
- 19 + 12539 = 12558
- 31 + 12527 = 12558
- 41 + 12517 = 12558
- 47 + 12511 = 12558
- 61 + 12497 = 12558
Showing the first eight; more decompositions exist.
