Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26580, here are decompositions:

  • 7 + 26573 = 26580
  • 19 + 26561 = 26580
  • 23 + 26557 = 26580
  • 41 + 26539 = 26580
  • 67 + 26513 = 26580
  • 79 + 26501 = 26580
  • 83 + 26497 = 26580
  • 101 + 26479 = 26580

Showing the first eight; more decompositions exist.
