Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77786, here are decompositions:

  • 3 + 77783 = 77786
  • 13 + 77773 = 77786
  • 43 + 77743 = 77786
  • 67 + 77719 = 77786
  • 73 + 77713 = 77786
  • 97 + 77689 = 77786
  • 127 + 77659 = 77786
  • 139 + 77647 = 77786

Showing the first eight; more decompositions exist.
