Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39580, here are decompositions:

  • 11 + 39569 = 39580
  • 17 + 39563 = 39580
  • 29 + 39551 = 39580
  • 59 + 39521 = 39580
  • 71 + 39509 = 39580
  • 137 + 39443 = 39580
  • 197 + 39383 = 39580
  • 239 + 39341 = 39580

Showing the first eight; more decompositions exist.
