Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8735728, here are decompositions:

  • 17 + 8735711 = 8735728
  • 47 + 8735681 = 8735728
  • 107 + 8735621 = 8735728
  • 179 + 8735549 = 8735728
  • 191 + 8735537 = 8735728
  • 311 + 8735417 = 8735728
  • 389 + 8735339 = 8735728
  • 479 + 8735249 = 8735728

Showing the first eight; more decompositions exist.
