Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77856, here are decompositions:

  • 7 + 77849 = 77856
  • 17 + 77839 = 77856
  • 43 + 77813 = 77856
  • 59 + 77797 = 77856
  • 73 + 77783 = 77856
  • 83 + 77773 = 77856
  • 109 + 77747 = 77856
  • 113 + 77743 = 77856

Showing the first eight; more decompositions exist.
