Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25842, here are decompositions:

  • 23 + 25819 = 25842
  • 41 + 25801 = 25842
  • 43 + 25799 = 25842
  • 71 + 25771 = 25842
  • 79 + 25763 = 25842
  • 83 + 25759 = 25842
  • 101 + 25741 = 25842
  • 109 + 25733 = 25842

Showing the first eight; more decompositions exist.
