Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631318, here are decompositions:

  • 11 + 8631307 = 8631318
  • 41 + 8631277 = 8631318
  • 67 + 8631251 = 8631318
  • 71 + 8631247 = 8631318
  • 89 + 8631229 = 8631318
  • 127 + 8631191 = 8631318
  • 151 + 8631167 = 8631318
  • 167 + 8631151 = 8631318

Showing the first eight; more decompositions exist.
