Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5178, here are decompositions:

  • 7 + 5171 = 5178
  • 11 + 5167 = 5178
  • 31 + 5147 = 5178
  • 59 + 5119 = 5178
  • 71 + 5107 = 5178
  • 79 + 5099 = 5178
  • 97 + 5081 = 5178
  • 101 + 5077 = 5178

Showing the first eight; more decompositions exist.
