Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77748, here are decompositions:

  • 5 + 77743 = 77748
  • 17 + 77731 = 77748
  • 29 + 77719 = 77748
  • 37 + 77711 = 77748
  • 59 + 77689 = 77748
  • 61 + 77687 = 77748
  • 67 + 77681 = 77748
  • 89 + 77659 = 77748

Showing the first eight; more decompositions exist.
