Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12912, here are decompositions:

  • 5 + 12907 = 12912
  • 13 + 12899 = 12912
  • 19 + 12893 = 12912
  • 23 + 12889 = 12912
  • 59 + 12853 = 12912
  • 71 + 12841 = 12912
  • 83 + 12829 = 12912
  • 89 + 12823 = 12912

Showing the first eight; more decompositions exist.
