Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671870, here are decompositions:

  • 59 + 8671811 = 8671870
  • 101 + 8671769 = 8671870
  • 131 + 8671739 = 8671870
  • 149 + 8671721 = 8671870
  • 173 + 8671697 = 8671870
  • 239 + 8671631 = 8671870
  • 281 + 8671589 = 8671870
  • 353 + 8671517 = 8671870

Showing the first eight; more decompositions exist.
