Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618250, here are decompositions:

  • 7 + 8618243 = 8618250
  • 13 + 8618237 = 8618250
  • 29 + 8618221 = 8618250
  • 37 + 8618213 = 8618250
  • 101 + 8618149 = 8618250
  • 103 + 8618147 = 8618250
  • 131 + 8618119 = 8618250
  • 163 + 8618087 = 8618250

Showing the first eight; more decompositions exist.
