Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671858, here are decompositions:

  • 47 + 8671811 = 8671858
  • 89 + 8671769 = 8671858
  • 137 + 8671721 = 8671858
  • 149 + 8671709 = 8671858
  • 227 + 8671631 = 8671858
  • 269 + 8671589 = 8671858
  • 347 + 8671511 = 8671858
  • 359 + 8671499 = 8671858

Showing the first eight; more decompositions exist.
