Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12474, here are decompositions:
- 17 + 12457 = 12474
- 23 + 12451 = 12474
- 37 + 12437 = 12474
- 41 + 12433 = 12474
- 53 + 12421 = 12474
- 61 + 12413 = 12474
- 73 + 12401 = 12474
- 83 + 12391 = 12474
Showing the first eight; more decompositions exist.
