Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8686980, here are decompositions:

  • 19 + 8686961 = 8686980
  • 79 + 8686901 = 8686980
  • 97 + 8686883 = 8686980
  • 103 + 8686877 = 8686980
  • 139 + 8686841 = 8686980
  • 151 + 8686829 = 8686980
  • 173 + 8686807 = 8686980
  • 251 + 8686729 = 8686980

Showing the first eight; more decompositions exist.
