Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728012, here are decompositions:

  • 23 + 8727989 = 8728012
  • 113 + 8727899 = 8728012
  • 233 + 8727779 = 8728012
  • 239 + 8727773 = 8728012
  • 281 + 8727731 = 8728012
  • 311 + 8727701 = 8728012
  • 353 + 8727659 = 8728012
  • 389 + 8727623 = 8728012

Showing the first eight; more decompositions exist.
