Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719238, here are decompositions:

  • 19 + 8719219 = 8719238
  • 61 + 8719177 = 8719238
  • 79 + 8719159 = 8719238
  • 97 + 8719141 = 8719238
  • 139 + 8719099 = 8719238
  • 181 + 8719057 = 8719238
  • 331 + 8718907 = 8719238
  • 379 + 8718859 = 8719238

Showing the first eight; more decompositions exist.
