Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77830, here are decompositions:

  • 17 + 77813 = 77830
  • 29 + 77801 = 77830
  • 47 + 77783 = 77830
  • 83 + 77747 = 77830
  • 107 + 77723 = 77830
  • 131 + 77699 = 77830
  • 149 + 77681 = 77830
  • 239 + 77591 = 77830

Showing the first eight; more decompositions exist.
