Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8674640, here are decompositions:

  • 97 + 8674543 = 8674640
  • 103 + 8674537 = 8674640
  • 109 + 8674531 = 8674640
  • 151 + 8674489 = 8674640
  • 157 + 8674483 = 8674640
  • 193 + 8674447 = 8674640
  • 241 + 8674399 = 8674640
  • 463 + 8674177 = 8674640

Showing the first eight; more decompositions exist.
