Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702080, here are decompositions:

  • 17 + 8702063 = 8702080
  • 29 + 8702051 = 8702080
  • 71 + 8702009 = 8702080
  • 83 + 8701997 = 8702080
  • 89 + 8701991 = 8702080
  • 131 + 8701949 = 8702080
  • 173 + 8701907 = 8702080
  • 197 + 8701883 = 8702080

Showing the first eight; more decompositions exist.
