Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747998, here are decompositions:

  • 11 + 8747987 = 8747998
  • 41 + 8747957 = 8747998
  • 71 + 8747927 = 8747998
  • 107 + 8747891 = 8747998
  • 167 + 8747831 = 8747998
  • 179 + 8747819 = 8747998
  • 191 + 8747807 = 8747998
  • 239 + 8747759 = 8747998

Showing the first eight; more decompositions exist.
