Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25940, here are decompositions:

  • 7 + 25933 = 25940
  • 37 + 25903 = 25940
  • 67 + 25873 = 25940
  • 73 + 25867 = 25940
  • 139 + 25801 = 25940
  • 181 + 25759 = 25940
  • 193 + 25747 = 25940
  • 199 + 25741 = 25940

Showing the first eight; more decompositions exist.
