Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8674668, here are decompositions:

  • 97 + 8674571 = 8674668
  • 131 + 8674537 = 8674668
  • 137 + 8674531 = 8674668
  • 157 + 8674511 = 8674668
  • 179 + 8674489 = 8674668
  • 269 + 8674399 = 8674668
  • 271 + 8674397 = 8674668
  • 307 + 8674361 = 8674668

Showing the first eight; more decompositions exist.
