Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671760, here are decompositions:

  • 127 + 8671633 = 8671760
  • 211 + 8671549 = 8671760
  • 241 + 8671519 = 8671760
  • 313 + 8671447 = 8671760
  • 367 + 8671393 = 8671760
  • 379 + 8671381 = 8671760
  • 397 + 8671363 = 8671760
  • 421 + 8671339 = 8671760

Showing the first eight; more decompositions exist.
