Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8216, here are decompositions:

  • 7 + 8209 = 8216
  • 37 + 8179 = 8216
  • 127 + 8089 = 8216
  • 157 + 8059 = 8216
  • 163 + 8053 = 8216
  • 199 + 8017 = 8216
  • 223 + 7993 = 8216
  • 283 + 7933 = 8216

Showing the first eight; more decompositions exist.
