Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25400, here are decompositions:

  • 43 + 25357 = 25400
  • 61 + 25339 = 25400
  • 79 + 25321 = 25400
  • 97 + 25303 = 25400
  • 139 + 25261 = 25400
  • 157 + 25243 = 25400
  • 163 + 25237 = 25400
  • 181 + 25219 = 25400

Showing the first eight; more decompositions exist.
