Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618230, here are decompositions:

  • 17 + 8618213 = 8618230
  • 83 + 8618147 = 8618230
  • 167 + 8618063 = 8618230
  • 197 + 8618033 = 8618230
  • 239 + 8617991 = 8618230
  • 281 + 8617949 = 8618230
  • 353 + 8617877 = 8618230
  • 359 + 8617871 = 8618230

Showing the first eight; more decompositions exist.
