Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25538, here are decompositions:

  • 67 + 25471 = 25538
  • 127 + 25411 = 25538
  • 181 + 25357 = 25538
  • 199 + 25339 = 25538
  • 229 + 25309 = 25538
  • 277 + 25261 = 25538
  • 349 + 25189 = 25538
  • 367 + 25171 = 25538

Showing the first eight; more decompositions exist.
