Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12498, here are decompositions:
- 7 + 12491 = 12498
- 11 + 12487 = 12498
- 19 + 12479 = 12498
- 41 + 12457 = 12498
- 47 + 12451 = 12498
- 61 + 12437 = 12498
- 89 + 12409 = 12498
- 97 + 12401 = 12498
Showing the first eight; more decompositions exist.
