Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12450, here are decompositions:
- 13 + 12437 = 12450
- 17 + 12433 = 12450
- 29 + 12421 = 12450
- 37 + 12413 = 12450
- 41 + 12409 = 12450
- 59 + 12391 = 12450
- 71 + 12379 = 12450
- 73 + 12377 = 12450
Showing the first eight; more decompositions exist.
