Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77798, here are decompositions:

  • 37 + 77761 = 77798
  • 67 + 77731 = 77798
  • 79 + 77719 = 77798
  • 109 + 77689 = 77798
  • 139 + 77659 = 77798
  • 151 + 77647 = 77798
  • 157 + 77641 = 77798
  • 181 + 77617 = 77798

Showing the first eight; more decompositions exist.
