Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5220, here are decompositions:

  • 11 + 5209 = 5220
  • 23 + 5197 = 5220
  • 31 + 5189 = 5220
  • 41 + 5179 = 5220
  • 53 + 5167 = 5220
  • 67 + 5153 = 5220
  • 73 + 5147 = 5220
  • 101 + 5119 = 5220

Showing the first eight; more decompositions exist.
