Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601870, here are decompositions:

  • 47 + 8601823 = 8601870
  • 97 + 8601773 = 8601870
  • 103 + 8601767 = 8601870
  • 127 + 8601743 = 8601870
  • 131 + 8601739 = 8601870
  • 163 + 8601707 = 8601870
  • 181 + 8601689 = 8601870
  • 223 + 8601647 = 8601870

Showing the first eight; more decompositions exist.
