Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642150, here are decompositions:

  • 3 + 8642147 = 8642150
  • 31 + 8642119 = 8642150
  • 43 + 8642107 = 8642150
  • 73 + 8642077 = 8642150
  • 163 + 8641987 = 8642150
  • 193 + 8641957 = 8642150
  • 241 + 8641909 = 8642150
  • 277 + 8641873 = 8642150

Showing the first eight; more decompositions exist.
