Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747938, here are decompositions:

  • 5 + 8747933 = 8747938
  • 11 + 8747927 = 8747938
  • 47 + 8747891 = 8747938
  • 107 + 8747831 = 8747938
  • 131 + 8747807 = 8747938
  • 149 + 8747789 = 8747938
  • 179 + 8747759 = 8747938
  • 191 + 8747747 = 8747938

Showing the first eight; more decompositions exist.
