Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668980, here are decompositions:

  • 7 + 8668973 = 8668980
  • 13 + 8668967 = 8668980
  • 29 + 8668951 = 8668980
  • 79 + 8668901 = 8668980
  • 83 + 8668897 = 8668980
  • 107 + 8668873 = 8668980
  • 149 + 8668831 = 8668980
  • 163 + 8668817 = 8668980

Showing the first eight; more decompositions exist.
