Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729712, here are decompositions:

  • 23 + 8729689 = 8729712
  • 31 + 8729681 = 8729712
  • 53 + 8729659 = 8729712
  • 71 + 8729641 = 8729712
  • 83 + 8729629 = 8729712
  • 109 + 8729603 = 8729712
  • 149 + 8729563 = 8729712
  • 283 + 8729429 = 8729712

Showing the first eight; more decompositions exist.
