Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12486, here are decompositions:

  • 7 + 12479 = 12486
  • 13 + 12473 = 12486
  • 29 + 12457 = 12486
  • 53 + 12433 = 12486
  • 73 + 12413 = 12486
  • 107 + 12379 = 12486
  • 109 + 12377 = 12486
  • 113 + 12373 = 12486

Showing the first eight; more decompositions exist.
