Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4220, here are decompositions:

  • 3 + 4217 = 4220
  • 19 + 4201 = 4220
  • 43 + 4177 = 4220
  • 61 + 4159 = 4220
  • 67 + 4153 = 4220
  • 109 + 4111 = 4220
  • 127 + 4093 = 4220
  • 163 + 4057 = 4220

Showing the first eight; more decompositions exist.
