Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38780, here are decompositions:

  • 13 + 38767 = 38780
  • 31 + 38749 = 38780
  • 43 + 38737 = 38780
  • 67 + 38713 = 38780
  • 73 + 38707 = 38780
  • 103 + 38677 = 38780
  • 109 + 38671 = 38780
  • 127 + 38653 = 38780

Showing the first eight; more decompositions exist.
