Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719842, here are decompositions:

  • 11 + 8719831 = 8719842
  • 23 + 8719819 = 8719842
  • 29 + 8719813 = 8719842
  • 41 + 8719801 = 8719842
  • 71 + 8719771 = 8719842
  • 139 + 8719703 = 8719842
  • 179 + 8719663 = 8719842
  • 181 + 8719661 = 8719842

Showing the first eight; more decompositions exist.
