Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691850, here are decompositions:

  • 17 + 8691833 = 8691850
  • 23 + 8691827 = 8691850
  • 47 + 8691803 = 8691850
  • 197 + 8691653 = 8691850
  • 227 + 8691623 = 8691850
  • 257 + 8691593 = 8691850
  • 263 + 8691587 = 8691850
  • 269 + 8691581 = 8691850

Showing the first eight; more decompositions exist.
