Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691928, here are decompositions:

  • 5 + 8691923 = 8691928
  • 101 + 8691827 = 8691928
  • 197 + 8691731 = 8691928
  • 239 + 8691689 = 8691928
  • 347 + 8691581 = 8691928
  • 419 + 8691509 = 8691928
  • 431 + 8691497 = 8691928
  • 449 + 8691479 = 8691928

Showing the first eight; more decompositions exist.
