Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5100, here are decompositions:

  • 13 + 5087 = 5100
  • 19 + 5081 = 5100
  • 23 + 5077 = 5100
  • 41 + 5059 = 5100
  • 61 + 5039 = 5100
  • 79 + 5021 = 5100
  • 89 + 5011 = 5100
  • 97 + 5003 = 5100

Showing the first eight; more decompositions exist.
