Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4950, here are decompositions:

  • 7 + 4943 = 4950
  • 13 + 4937 = 4950
  • 17 + 4933 = 4950
  • 19 + 4931 = 4950
  • 31 + 4919 = 4950
  • 41 + 4909 = 4950
  • 47 + 4903 = 4950
  • 61 + 4889 = 4950

Showing the first eight; more decompositions exist.
