Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671080, here are decompositions:

  • 13 + 8671067 = 8671080
  • 17 + 8671063 = 8671080
  • 23 + 8671057 = 8671080
  • 29 + 8671051 = 8671080
  • 71 + 8671009 = 8671080
  • 73 + 8671007 = 8671080
  • 83 + 8670997 = 8671080
  • 137 + 8670943 = 8671080

Showing the first eight; more decompositions exist.
