Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690938, here are decompositions:

  • 17 + 8690921 = 8690938
  • 71 + 8690867 = 8690938
  • 149 + 8690789 = 8690938
  • 197 + 8690741 = 8690938
  • 449 + 8690489 = 8690938
  • 461 + 8690477 = 8690938
  • 587 + 8690351 = 8690938
  • 647 + 8690291 = 8690938

Showing the first eight; more decompositions exist.
