Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6580, here are decompositions:

  • 3 + 6577 = 6580
  • 11 + 6569 = 6580
  • 17 + 6563 = 6580
  • 29 + 6551 = 6580
  • 59 + 6521 = 6580
  • 89 + 6491 = 6580
  • 107 + 6473 = 6580
  • 131 + 6449 = 6580

Showing the first eight; more decompositions exist.
