Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691556, here are decompositions:

  • 47 + 8691509 = 8691556
  • 59 + 8691497 = 8691556
  • 149 + 8691407 = 8691556
  • 173 + 8691383 = 8691556
  • 197 + 8691359 = 8691556
  • 257 + 8691299 = 8691556
  • 317 + 8691239 = 8691556
  • 347 + 8691209 = 8691556

Showing the first eight; more decompositions exist.
