Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691906, here are decompositions:

  • 5 + 8691901 = 8691906
  • 17 + 8691889 = 8691906
  • 23 + 8691883 = 8691906
  • 53 + 8691853 = 8691906
  • 73 + 8691833 = 8691906
  • 79 + 8691827 = 8691906
  • 103 + 8691803 = 8691906
  • 107 + 8691799 = 8691906

Showing the first eight; more decompositions exist.
