Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19580, here are decompositions:

  • 3 + 19577 = 19580
  • 37 + 19543 = 19580
  • 73 + 19507 = 19580
  • 79 + 19501 = 19580
  • 97 + 19483 = 19580
  • 103 + 19477 = 19580
  • 109 + 19471 = 19580
  • 139 + 19441 = 19580

Showing the first eight; more decompositions exist.
