Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61580, here are decompositions:

  • 19 + 61561 = 61580
  • 37 + 61543 = 61580
  • 61 + 61519 = 61580
  • 73 + 61507 = 61580
  • 97 + 61483 = 61580
  • 109 + 61471 = 61580
  • 139 + 61441 = 61580
  • 163 + 61417 = 61580

Showing the first eight; more decompositions exist.
