Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8116, here are decompositions:

  • 5 + 8111 = 8116
  • 23 + 8093 = 8116
  • 29 + 8087 = 8116
  • 47 + 8069 = 8116
  • 107 + 8009 = 8116
  • 167 + 7949 = 8116
  • 179 + 7937 = 8116
  • 197 + 7919 = 8116

Showing the first eight; more decompositions exist.
