Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513732, here are decompositions:

  • 5 + 513727 = 513732
  • 13 + 513719 = 513732
  • 41 + 513691 = 513732
  • 53 + 513679 = 513732
  • 59 + 513673 = 513732
  • 83 + 513649 = 513732
  • 101 + 513631 = 513732
  • 139 + 513593 = 513732

Showing the first eight; more decompositions exist.
