Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718658, here are decompositions:

  • 167 + 8718491 = 8718658
  • 197 + 8718461 = 8718658
  • 227 + 8718431 = 8718658
  • 239 + 8718419 = 8718658
  • 251 + 8718407 = 8718658
  • 257 + 8718401 = 8718658
  • 281 + 8718377 = 8718658
  • 461 + 8718197 = 8718658

Showing the first eight; more decompositions exist.
