Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4818, here are decompositions:

  • 5 + 4813 = 4818
  • 17 + 4801 = 4818
  • 19 + 4799 = 4818
  • 29 + 4789 = 4818
  • 31 + 4787 = 4818
  • 59 + 4759 = 4818
  • 67 + 4751 = 4818
  • 89 + 4729 = 4818

Showing the first eight; more decompositions exist.
