Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25838, here are decompositions:

  • 19 + 25819 = 25838
  • 37 + 25801 = 25838
  • 67 + 25771 = 25838
  • 79 + 25759 = 25838
  • 97 + 25741 = 25838
  • 181 + 25657 = 25838
  • 199 + 25639 = 25838
  • 229 + 25609 = 25838

Showing the first eight; more decompositions exist.
