Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742806, here are decompositions:

  • 19 + 8742787 = 8742806
  • 67 + 8742739 = 8742806
  • 229 + 8742577 = 8742806
  • 277 + 8742529 = 8742806
  • 307 + 8742499 = 8742806
  • 313 + 8742493 = 8742806
  • 337 + 8742469 = 8742806
  • 439 + 8742367 = 8742806

Showing the first eight; more decompositions exist.
