Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605880, here are decompositions:

  • 7 + 8605873 = 8605880
  • 37 + 8605843 = 8605880
  • 67 + 8605813 = 8605880
  • 79 + 8605801 = 8605880
  • 271 + 8605609 = 8605880
  • 313 + 8605567 = 8605880
  • 337 + 8605543 = 8605880
  • 379 + 8605501 = 8605880

Showing the first eight; more decompositions exist.
