Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629986, here are decompositions:

  • 5 + 8629981 = 8629986
  • 23 + 8629963 = 8629986
  • 37 + 8629949 = 8629986
  • 59 + 8629927 = 8629986
  • 97 + 8629889 = 8629986
  • 103 + 8629883 = 8629986
  • 139 + 8629847 = 8629986
  • 163 + 8629823 = 8629986

Showing the first eight; more decompositions exist.
