Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77824, here are decompositions:

  • 11 + 77813 = 77824
  • 23 + 77801 = 77824
  • 41 + 77783 = 77824
  • 101 + 77723 = 77824
  • 113 + 77711 = 77824
  • 137 + 77687 = 77824
  • 233 + 77591 = 77824
  • 251 + 77573 = 77824

Showing the first eight; more decompositions exist.
