Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25658, here are decompositions:

  • 19 + 25639 = 25658
  • 37 + 25621 = 25658
  • 79 + 25579 = 25658
  • 97 + 25561 = 25658
  • 211 + 25447 = 25658
  • 337 + 25321 = 25658
  • 349 + 25309 = 25658
  • 397 + 25261 = 25658

Showing the first eight; more decompositions exist.
