Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700580, here are decompositions:

  • 17 + 8700563 = 8700580
  • 41 + 8700539 = 8700580
  • 59 + 8700521 = 8700580
  • 107 + 8700473 = 8700580
  • 113 + 8700467 = 8700580
  • 131 + 8700449 = 8700580
  • 149 + 8700431 = 8700580
  • 173 + 8700407 = 8700580

Showing the first eight; more decompositions exist.
