Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12522, here are decompositions:
- 5 + 12517 = 12522
- 11 + 12511 = 12522
- 19 + 12503 = 12522
- 31 + 12491 = 12522
- 43 + 12479 = 12522
- 71 + 12451 = 12522
- 89 + 12433 = 12522
- 101 + 12421 = 12522
Showing the first eight; more decompositions exist.
