Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719020, here are decompositions:

  • 17 + 8719003 = 8719020
  • 47 + 8718973 = 8719020
  • 67 + 8718953 = 8719020
  • 71 + 8718949 = 8719020
  • 103 + 8718917 = 8719020
  • 113 + 8718907 = 8719020
  • 139 + 8718881 = 8719020
  • 151 + 8718869 = 8719020

Showing the first eight; more decompositions exist.
