Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673980, here are decompositions:

  • 67 + 8673913 = 8673980
  • 79 + 8673901 = 8673980
  • 103 + 8673877 = 8673980
  • 163 + 8673817 = 8673980
  • 199 + 8673781 = 8673980
  • 277 + 8673703 = 8673980
  • 379 + 8673601 = 8673980
  • 409 + 8673571 = 8673980

Showing the first eight; more decompositions exist.
