Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719886, here are decompositions:

  • 13 + 8719873 = 8719886
  • 67 + 8719819 = 8719886
  • 73 + 8719813 = 8719886
  • 139 + 8719747 = 8719886
  • 223 + 8719663 = 8719886
  • 283 + 8719603 = 8719886
  • 313 + 8719573 = 8719886
  • 337 + 8719549 = 8719886

Showing the first eight; more decompositions exist.
