Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668672, here are decompositions:

  • 29 + 8668643 = 8668672
  • 59 + 8668613 = 8668672
  • 101 + 8668571 = 8668672
  • 149 + 8668523 = 8668672
  • 251 + 8668421 = 8668672
  • 269 + 8668403 = 8668672
  • 293 + 8668379 = 8668672
  • 479 + 8668193 = 8668672

Showing the first eight; more decompositions exist.
