Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2748, here are decompositions:

  • 7 + 2741 = 2748
  • 17 + 2731 = 2748
  • 19 + 2729 = 2748
  • 29 + 2719 = 2748
  • 37 + 2711 = 2748
  • 41 + 2707 = 2748
  • 59 + 2689 = 2748
  • 61 + 2687 = 2748

Showing the first eight; more decompositions exist.
