Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12560, here are decompositions:

  • 7 + 12553 = 12560
  • 13 + 12547 = 12560
  • 19 + 12541 = 12560
  • 43 + 12517 = 12560
  • 73 + 12487 = 12560
  • 103 + 12457 = 12560
  • 109 + 12451 = 12560
  • 127 + 12433 = 12560

Showing the first eight; more decompositions exist.
