Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615470, here are decompositions:

  • 47 + 8615423 = 8615470
  • 137 + 8615333 = 8615470
  • 191 + 8615279 = 8615470
  • 197 + 8615273 = 8615470
  • 233 + 8615237 = 8615470
  • 239 + 8615231 = 8615470
  • 251 + 8615219 = 8615470
  • 293 + 8615177 = 8615470

Showing the first eight; more decompositions exist.
