Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615170, here are decompositions:

  • 71 + 8615099 = 8615170
  • 107 + 8615063 = 8615170
  • 191 + 8614979 = 8615170
  • 197 + 8614973 = 8615170
  • 257 + 8614913 = 8615170
  • 269 + 8614901 = 8615170
  • 281 + 8614889 = 8615170
  • 383 + 8614787 = 8615170

Showing the first eight; more decompositions exist.
