Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4912, here are decompositions:

  • 3 + 4909 = 4912
  • 23 + 4889 = 4912
  • 41 + 4871 = 4912
  • 113 + 4799 = 4912
  • 179 + 4733 = 4912
  • 191 + 4721 = 4912
  • 233 + 4679 = 4912
  • 239 + 4673 = 4912

Showing the first eight; more decompositions exist.
