Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 732, here are decompositions:

  • 5 + 727 = 732
  • 13 + 719 = 732
  • 23 + 709 = 732
  • 31 + 701 = 732
  • 41 + 691 = 732
  • 59 + 673 = 732
  • 71 + 661 = 732
  • 73 + 659 = 732

Showing the first eight; more decompositions exist.
