Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719844, here are decompositions:

  • 13 + 8719831 = 8719844
  • 31 + 8719813 = 8719844
  • 43 + 8719801 = 8719844
  • 73 + 8719771 = 8719844
  • 97 + 8719747 = 8719844
  • 163 + 8719681 = 8719844
  • 181 + 8719663 = 8719844
  • 241 + 8719603 = 8719844

Showing the first eight; more decompositions exist.
