Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12480, here are decompositions:
- 7 + 12473 = 12480
- 23 + 12457 = 12480
- 29 + 12451 = 12480
- 43 + 12437 = 12480
- 47 + 12433 = 12480
- 59 + 12421 = 12480
- 67 + 12413 = 12480
- 71 + 12409 = 12480
Showing the first eight; more decompositions exist.
