Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691528, here are decompositions:

  • 19 + 8691509 = 8691528
  • 31 + 8691497 = 8691528
  • 47 + 8691481 = 8691528
  • 59 + 8691469 = 8691528
  • 137 + 8691391 = 8691528
  • 229 + 8691299 = 8691528
  • 277 + 8691251 = 8691528
  • 281 + 8691247 = 8691528

Showing the first eight; more decompositions exist.
