Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4788, here are decompositions:

  • 5 + 4783 = 4788
  • 29 + 4759 = 4788
  • 37 + 4751 = 4788
  • 59 + 4729 = 4788
  • 67 + 4721 = 4788
  • 97 + 4691 = 4788
  • 109 + 4679 = 4788
  • 131 + 4657 = 4788

Showing the first eight; more decompositions exist.
