Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669090, here are decompositions:

  • 7 + 8669083 = 8669090
  • 19 + 8669071 = 8669090
  • 97 + 8668993 = 8669090
  • 139 + 8668951 = 8669090
  • 193 + 8668897 = 8669090
  • 277 + 8668813 = 8669090
  • 307 + 8668783 = 8669090
  • 349 + 8668741 = 8669090

Showing the first eight; more decompositions exist.
