Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666678, here are decompositions:

  • 199 + 8666479 = 8666678
  • 331 + 8666347 = 8666678
  • 409 + 8666269 = 8666678
  • 541 + 8666137 = 8666678
  • 619 + 8666059 = 8666678
  • 661 + 8666017 = 8666678
  • 739 + 8665939 = 8666678
  • 829 + 8665849 = 8666678

Showing the first eight; more decompositions exist.
