Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745724, here are decompositions:

  • 41 + 8745683 = 8745724
  • 47 + 8745677 = 8745724
  • 167 + 8745557 = 8745724
  • 173 + 8745551 = 8745724
  • 521 + 8745203 = 8745724
  • 563 + 8745161 = 8745724
  • 653 + 8745071 = 8745724
  • 773 + 8744951 = 8745724

Showing the first eight; more decompositions exist.
