Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12492, here are decompositions:
- 5 + 12487 = 12492
- 13 + 12479 = 12492
- 19 + 12473 = 12492
- 41 + 12451 = 12492
- 59 + 12433 = 12492
- 71 + 12421 = 12492
- 79 + 12413 = 12492
- 83 + 12409 = 12492
Showing the first eight; more decompositions exist.
