Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742700, here are decompositions:

  • 11 + 8742689 = 8742700
  • 23 + 8742677 = 8742700
  • 47 + 8742653 = 8742700
  • 149 + 8742551 = 8742700
  • 251 + 8742449 = 8742700
  • 347 + 8742353 = 8742700
  • 353 + 8742347 = 8742700
  • 383 + 8742317 = 8742700

Showing the first eight; more decompositions exist.
