Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493780, here are decompositions:

  • 3 + 493777 = 493780
  • 47 + 493733 = 493780
  • 59 + 493721 = 493780
  • 71 + 493709 = 493780
  • 137 + 493643 = 493780
  • 173 + 493607 = 493780
  • 197 + 493583 = 493780
  • 239 + 493541 = 493780

Showing the first eight; more decompositions exist.
