Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25156, here are decompositions:

  • 3 + 25153 = 25156
  • 29 + 25127 = 25156
  • 59 + 25097 = 25156
  • 83 + 25073 = 25156
  • 167 + 24989 = 25156
  • 179 + 24977 = 25156
  • 233 + 24923 = 25156
  • 239 + 24917 = 25156

Showing the first eight; more decompositions exist.
